Top 10 JavaScript Console Methods for Effective Debugging
JavaScript Console methods are functions provided by JavaScript’s ‘console’ object. These functions enable web developers to access the debugging console in web browsers. In short, they improve the debugging process by letting developers perform different debugging and logging tasks. For instance, they can track the performance of their web codes, output information, and inspect objects and arrays. This post makes you familiar with some crucial JavaScript console methods. Let’s begin. 1. Log Method The console.log() method is one of the primary JavaScript console methods. It allows developers to print numbers, strings, JavaScript variables, or objects in the console. Besides, it logs messages to the debugging terminal rather than displaying them in the browser console. console.log('Hello, world'); console.log({ name: 'Alice', age: 30 }); 2. Info Method The method console.info() is similar to console.log(). It helps developers print information needed for debugging purposes rather than printing values. console.info('This is an informatinal message'); 3. Debug Method The console.log(), console.info(), and console.debug() look similar. Nevertheless, their output visibility in the browser console is different. The browser defines color codes to console method output messages. The output from the console.debug() method does not show in Chrome developer tools by default. Users must enable the console filter option for all levels to see the output from the debug method. console.debug('Debugging message'); 4. Warn Method The console.warn() method allows developers to display a warning message in the console. The message can be anything from an object to an array, to a variable. Generally, warning messages are highlighted with a yellow icon. Therefore, they look different from regular log messages. The message appears in the browser as a warning indicator. console.warn('This is a warning message'); 5. Assert Method The console.assert() method is different from the above-mentioned methods. This console method is used for testing purposes. It evaluates a given expression. If the expression results in ‘false’, it writes an error message to the console.. The console method helps in debugging by verifying certain conditions. console.assert(1 === 2, 'This will fail'); 6. Count Method As the name suggests, the console.count() method is a log counter. It logs the number of times the console.count() method has been called in a script. The console method is useful for tracking how many times a particular code is executed. console.count(label); console.count(label); label (Optional): A string label to identify the count. If there is no label, the default label ‘default’ is used. It’s usage examples are as follow: console.count("myLabel"); // Output: myLabel: 1 console.count("myLabel"); // Output: myLabel: 2 console.count("myLabel"); // Output: myLabel: 3 console.count(); // Output: default: 1 console.count(); // Output: default: 2 In the above example, calling ‘console.count(“myLabel”) three times increments the count for the label “myLabel”. Similarly, calling ‘console.count()’ without a label increments the count for the default label. 7. Trace Method The console.trace() method in JavaScript helps developers output a stack trace to the console. It provides a report of the active stack frames at a particular point in time. The console method shows the path of the execution which led to the current line of code. This debugging purpose helps developers learn how a particular code was reached. Syntax console.trace(label); Label(Optional): A string label appears at the beginning of the stack trace. Example function firstFunction(){ secondFunction(); } function secondFunction(){ thirdFunction(); } function thirdFunction(){ console.trace("Tracking the call stack:"); } firstFunction(); Output Tracking the call stack: at thirdFunction (<anonymous>:10:13) at secondFunction (<anonymous>:10:13) at firstFunction (<anonymous>:10:13) at <anonymous>:14:1 In this example, calling ‘console.trace (“Tracking the call stack:”)’ inside thirdFunction outputs the stack trace to the console, showing the sequence of function calls that led to thirdFunction. 8. Time, TimeLog and TimeEnd Methods The ‘Time’, ‘TimeLog’, and ‘TimeEnd’ are popular JavaScript console methods. Developers use them to measure and log the duration of code execution in programming. Time Method The time method starts the timer and records the time. Developers can calculate the exact duration of a particular operation through this method. TimeLog Method The ‘TimeLog’ method logs the current time along with the elapsed time from the call of the ‘Time’ method. It is quite helpful for recording intermediate steps in a long-running process to learn how long a particular step takes. TimeEnd Method As the name indicates, the ‘TimeEnd’ method stops the timer. It logs the total time since the ‘Time’ method was called. This method gives you a record of the total duration of the operation. console.time('process'); // Start the timer // Code block whose duration you want to measure for (let 1 = 0; i < 1000000; i++) { // Some time-consuming task } console.timeLog('process'); // Log the intermediate time // Another code block for (let i = 0; i <1000000; i++){ // Another time-consuming task } console.timeEnd('process'); // End the timer and log the total time Output process: 10ms process: 15ms process: 20ms 9. Table method The JavaScript ‘console.table()’ method displays tabular data in the console. It is quite useful to visualize an array of objects in an organized way. It helps users understand data in a better way. After all, they can sort columns fast. const data = [ { name: "John", age: 30, city: "New York"}, { name: "Jane", age: 25, city: "San Francisco"}, { name: "Mike", age:32, city: "Chicago"} ]; console.table(data); Output 10. Clear Method The clear method in JavaScript helps developers clear the console. If you want to delete all your previous logs and start fresh, you can use this console command. console.log("This is a log message"); console.log("Another log message"); // Clear the console console.clear(); console.log("This is a log message after clearing the console"); Output This is a log message Another log message This is a log message after clearing the console As soon as the console.clear() is called, the console gets cleared. Only log messages are visible now. Final Words Undoubtedly, there are
Everything You Need to Know About Axios Interceptors
Managing HTTP requests and responses is quite challenging in modern web development. Fortunately, Axios is a robust JavaScript library that simplifies this process by offering a clean API. Axios is a promise-based HTTP client that features a simple intuitive API for sending HTTP requests and handling responses. Interceptors are a primary feature of Axios, helping users modify HTTP requests and responses quickly. This post makes you familiar with Axios interceptors and their roles in web development. So without any further delay, let us get started. What are Axios Interceptors? Axios interceptors are middleware functions that allow you to intercept requests before the primary application logic handles them. These functions are called before a request is sent and after a response is received. They provide a way to control and modify the requests and responses that are sent and received by an application. You can use Axios interceptors to alter requests, manage errors, add headers, and more. We can divide Axios interceptors into two types: Request Interceptors These interceptors are executed before a request is sent. They enable you to change the request configuration or add authentication tokens and headers. Response Interceptors As the name suggests, response interceptors are executed upon receiving a response. They allow you to intercept and handle the response before it gets passed to the calling code. These interceptors are quite useful for managing tasks like data transformation and error handling. How Do Interceptors Improve API Interactions? Interceptors can enhance your API interactions significantly. You can leverage interceptors in the following ways. Centralize Common Functionality With Interceptor, you do not need to repeat the same code across multiple API calls. You can encapsulate shared logic in interceptors. It supports code reusability and maintainability. Improved Security Interceptors help you add authentication headers automatically. Besides this, you can manage token refreshing and implement other security measures. Data Transformation You can transform request and response data before it reaches your application logic. Authentication & Authorization Individuals can also use interceptors to attach authentication tokens to requests. It makes sure that all outgoing requests carry the necessary credentials. If a token expires, the interceptor redirects the user to the login page. Use Cases of Axios Interceptors Adding Authentication Headers Axios interceptors let you inject authentication headers impeccably into outgoing requests. This feature is useful for APIs that need authorization tokens or API keys. import axios from 'axios'; const instance = axios.create({ baseURL: 'https://api.example.com', }); instance.interceptors.request.use(config => { const token = localStorage.getItem('authToken'); if (token) { config.headers.Authorization = `Bearer ${token}`; } return config; }); export default instance; Handling Errors You can also use interceptors to manage errors uniformly throughout your application. Developers can make an error interceptor to find and handle common error responses from the application programming interface. import axios from 'axios'; const instance = axios.create({ baseURL: 'https://api.example.com', }); instance.interceptors.response.use( response => response, error => { if (error.response) { if (error.response.status === 401) { // Redirect to login page } else if (error.response.status === 404) { // Redirect to 404 page } } return Promise.reject(error); } ); export default instance; Refreshing Tokens Interceptors also help in refreshing expired authentication tokens. When an API responds with a 401 status, the interceptor catches this response and sends a request for refreshing the token. axiosInstance.interceptors.response.use( response => response, async error => { if (error.response.status === 401) { const originalRequest = error.config; const refreshToken = localStorage.getItem('refreshToken'); try { const response = await axios.post('/auth/refresh-token', { token: refreshToken }); localStorage.setItem('token', response.data.token); originalRequest.headers.Authorization = `Bearer ${response.data.token}`; return axios(originalRequest); } catch (e) { console.error('Refresh token failed:', e); window.location.href = '/login'; return Promise.reject(e); } } return Promise.reject(error); } ); Loading Indicators & Cancellation Interceptors can take the user experience of your application to the next level. They provide a loading indicator during API requests. Besides this, interceptors let you implement request cancellation to prevent unnecessary network traffic. import axios from 'axios'; const instance = axios.create({ baseURL: 'https://api.example.com', }); let activeRequests = 0; instance.interceptors.request.use(config => { activeRequests++; // Show loading indicator return config; }); instance.interceptors.response.use( response => { activeRequests–; if (activeRequests === 0) { // Hide loading indicator } return response; }, error => { activeRequests–; if (activeRequests === 0) { // Hide loading indicator } return Promise.reject(error); } ); export default instance; Final Words Interceptors in Axios enable developers to intercept and modify HTTP requests and responses. From handling errors to adding headers to managing token expiry, they help you create an efficient and user-friendly application. Using interceptors, web developers can empower their applications to manage network interactions securely and smoothly. Axios interceptors can help whether you want to handle a simple request modification or a complex token refresh mechanism. So if you are a JavaScript developer working on an application that communicates with APIs, leverage the power of Axios interceptors.

Kuto Bundler: A Quick Guide to its Features and Implementation
Excellent user experience, quick load time, and lean codes are crucial for gaining success in modern web development. JavaScript bundling has been a prominent tool for optimizing web performance. However, it has some limitations. Slow updates and bloated bundles are a few issues people often complain about. Kuto Bundler seems like a revolutionary solution to overcome these flaws. Unlike conventional bundlers, it takes a reverse approach to bundling, resulting in fast load times and optimization. This tool streamlines the bundling process and manages dependencies in JavaScript. Let us get to know more about Kuto Bundler and its features Overview of Kuto Bundler Kuto is a reverse JS (JavaScript) bundler that helps users make websites faster by dividing code into separate bundles. The bundler supports quick updates without redownloading the entire bundle. Kuto employs caching optimizations and intelligent splitting to reduce the size of a bundle. It naturally improves the update efficiency. Furthermore, Kuto lets users customize the bundling process according to their preferences. Key Features of Kuto Bundler Kuto is gaining popularity for its reduced download size and start time. When updating a React component on a site with approximately 3MB of JavaScript, there was a 71% decrease in data required to be downloaded. Besides this, the site started almost 28% faster even on Pixel 3 which is a pretty old device now. Let us check out some exciting features of Kuto “No Side Effects” Function Kuto bundle searches for codes with no side effects and adds them to its corpuses. The tool employs circular dependencies to make sure codes are safe to call. The bundler ensures that the process of bundling JavaScript code can’t modify any external state or variables outside the code being bundled. It prevents unexpected disruption to different parts of the web application. Circular Dependency Kuto has a mechanism to identify and manage circular dependencies. It issues warning alerts to developers about such problems. Additionally, Kuto might recommend code restructuring to resolve the situation of circular dependencies. Code Splitting Kuto Bundler lets web developers implement code splitting. They can divide their codebase into small and easy-to-manage chunks.

Why is Low-code Platform a bad choice in Development?
Low-code or no-code web development is in trend. It enables users to build applications in less time with minimal or no coding. However, these quick development facilities often come with consequences. Although they limit individuals’ dependency on web developers, low-code platforms are not always a good choice. Wondering when you should avoid these platforms? Read this post until the end. Before we proceed further, let us learn what a low-code platform is. What are Low-Code Web Development Platforms? As the name suggests, a low-code platform lets people develop websites or mobile applications with minimal coding. Since it is affordable and requires limited technical knowledge, numerous people and companies prefer to use it. Tilda, UIPath, Adalo, and Webflow are some popular low-code platforms. Unfortunately, these platforms have numerous benefits but come with some limitations. Limitations of Low-Code/No-Cod Web Development You Can’t make What Exactly You Desire With most low-code or no-code platforms, you cannot build a website/mobile application that specifically meets your requirements. They can help you make a simple landing page with limited features. However, if you want to create a complicated business application, it will be challenging to get the desired results. These platforms always come with templates that do not align with particular requirements. Compromised Security Another issue with low-code platforms is compromised security. Since cyber-attacks are increasing day by day, security is a primary concern in web development. No company wants a website or an app, which is at risk of cyber-attacks. These platforms come with pre-designed templates that might have inherent weaknesses. Hackers might exploit these vulnerabilities. When you opt for custom web development services through certified professionals, you naturally minimize security inadequacies. Furthermore, web developers can integrate powerful encryption and security protocols to ensure the security of your app/website. Limited Customization If you want to develop an application that stands out from the crowd, a low-code development service won’t be a good choice. In most cases, they have fixed templates with minimum customization options. You won’t be able to modify several aspects of your app. The lack of integration options might frustrate you in the long run. So if you have complex requirements, consider taking traditional software development services. Poor Performance Low-code/no-code web development relies on pre-built components to perform. Consequently, it might face issues like slow loading and inadequacies. These small things lead to poor user experience and bounce rate. No Proper Control Lack of control of the application is one of the biggest downsides of low-code platforms. Users have to adhere to the policies of the low-code development service providers. Sometimes, these restrictions can go against users. Since you do not have control and ownership over these low-code development services, you can’t do much about them if they suddenly increase service fees. Sometimes, they discontinue the features that are crucial for your business. No Access to Codes There are situations when you have to access the web codes of your website or application. Unfortunately, low-code platforms limit access to codes. As a result, it can be challenging to modify the application. Even if you ever migrate your app to other no-code platforms, your existing service provider might restrict access. Inconsistent Appearance The aesthetics of a website or web application is quite important. It acts as a virtual storefront for businesses. Elements, grids, colors, there are numerous aspects to take care of. With pre-build design templates, you can’t get the exact appearance you want. Final Words: Are Low-Code Web Development Platforms Worth it? Undoubtedly, low-code or no-code platforms come with a lot of compelling features. They are easy to use and affordable. Nevertheless, you can’t neglect their drawbacks. People looking for customized web solutions for their business or brand must ignore these platforms. If you are developing software or an app that requires security compliance, no-code web development options can expose you to risks. Furthermore, they don’t give you complete control over the code base. If you think only low code development can fulfill all your business requirements, you are mistaken. Beyond the simple use case, you will need to hire developers. Consequently, custom web development services are always a better choice. Of course, you spend some extra dollars, but you get a feature-rich, safe, and high-performance website or application. If you want to empower your brand and set it apart from the competition without compromising on security, choose Almas web development services.

How Much It Costs to Build a Minimum Viable Product (MVP)
Today businesses and startups keep introducing new products to capture the market share. They take a Minimum Viable Product (MVP) approach to launch their web applications. After all, releasing the simple version of an app lets you test it better. Nevertheless, how much does it cost to create an MVP? Numerous startups have this question in their minds. In this post, we learn about the factors that influence the price of MVP. It will give you an idea about the budget you should arrange for your next MVP. So without any further delay, let’s start it. Factors Affecting the Price of Building a Minimum Viable Product Building an MVP is comparatively more affordable than an actual product. Furthermore, it helps you set budget expectations and secure funding. In short, you can create a clear financial plan for your project. Let’s discuss the aspects that may affect the cost of an MVP. Features of MVP The features and complexity of your MVP play a crucial role in determining the overall cost. If you are making a simple pilot product with basic features and functionality, the cost will be low. The web application with complex features, data processing, and API integrations requires a substantial budget. UI/UX Design User Interface and User Experience also influence the cost of an MVP to a great extent. UI and UX determine how your target audience interacts with your product. If your application’s visual appeal and functionality cannot retain users, you can’t expect to get the desired results. As a result, you must allocate some budget, particularly for UI/UX design. If your product/web application requires comprehensive wireframing and prototyping, it will naturally increase the overall price. Software & Web Technologies The type of programming languages, libraries, and frameworks you use also affects the price. Besides this, the license fee for software pieces increases the product cost. If you want to do cost-cutting in this part, choose cross-platform frameworks rather than native technologies. Nevertheless, do not compromise on the functionality and scalability requirements of the app. Cost to Hire a Development Team The cost of hiring a web development team depends on various factors. We have listed some of them below: Team Size The number of members a development team has affects the cost. If you need a large team, you will have to pay accordingly. Experience Besides the size of the team, expertise and experience level of developers also influence the cost. A skilled and experienced professional often has a higher fee than a newbie. If you also need testers or data engineers, the project cost will rise. Location of the Team Web developers from the United States and Europe may charge more than programmers from Asia. So consider the geographical location of experts when hiring them. In addition to this, you may also determine choosing between freelancers and an in-house team. Do not forget that getting an on-site team entails additional expenses apart from their salary. Overall Development Timeframe of the Product How long it would take to develop a minimum viable product depends on various factors. The number of programmers, availability of resources, and complexity of the applications are a few common aspects. Besides, numerous technological challenges can impact the timeframe. The shorter the timeframe for building an MVP is, the more cost-effective it will be. The Possible Hidden Charges for Building an MVP In addition to the above evident expenses, you may have to bear some unforeseen expenses. These could be: Quality Testing Once your MVP is built, it is tested for proper functionality and a pleasing user experience. You will have to hire a vendor to obtain a QA testing service and certification. Performance Optimization As your user base increases, you will need to scale and optimize the performance of your MVP. For example, you might need to invest in a high-capacity hosting server, load balancers, and caching tools. Integration of 3rd Party Services In some cases, your application may require third-party integration. It can be an API, Plugin, or any external platform. These services can have monthly fees or license costs. Local and International Marketing Determine whether you want to target the global or local market. Depending on your target audience, make your application compatible with a particular language. These small things also impact the cost of the product. Maintenance Even after your application is officially launched, it requires regular improvement and maintenance. The cost of maintenance might go up to 20% of the overall MVP development cost per year. Marketing Your product cannot succeed if it does not reach the right audience. Therefore, you need to spend on marketing techniques too. You will have to create a budget for social media advertising, content marketing, and search engine optimization. Quick Tips to Minimize the Cost of an MVP Go for web application-building platforms that require minimal coding. Use open-source libraries & frameworks to avoid license fees. For instance, React Native and Flutter are two open-source frameworks that you can use to build iOS & Android-based mobile applications. To manage the scalability requirements of your app, prefer cloud-based development platforms like AWS and Azure. Consider outsourcing your MVP app development. It will be several times cheaper than hiring an in-house team. Final Words Building an MVP is an ideal way to bring an idea to life. Nevertheless, before you progress, you must be aware of potential expenditures.

React Performance: Best Techniques to Optimize It in 2024
React is one of the renowned JavaScript libraries. While it supports a decent rendering mechanism, it sometimes needs performance optimization. If you are making a complex application that requires more scalability and security, try the following performance optimization techniques. Before we discuss these methods, let’s learn some primary concepts of React performance. VDOM React employs a Virtual DOM, also known as VDOM, to enhance its performance. When you make changes to your app, React updates the VDOM. So you can compare the changes easily. Reconciliation Reconciliation is the process React uses to update the DOM and match the current component tree. It recognizes the differences by comparing the old VDOM with the new one. It gives updates on the DOM parts that have been modified. Techniques to Optimize React Performance Implement React. memo () React.memo tool helps you prevent unnecessary component rendering when the props received in that component do not change. It enhances the application’s performance to a great extent. Implementing React.memo is easy. See the following example. import { memo } from "react"; import { MyComponent } from "./MyComponent"; export const App = () => { // using a component const MemoizedComponent = memo(MyComponent); // using a function expression const MemoizedComponent2 = memo(function ({ data }) { return <div>Some interesting {data}</div>; }); // using an arrow function const MemoizedComponent3 = memo(({ data }) => { return <div>Some interesting {data}</div>; }); const someDataPassedAsProp = {}; return <MemoizedComponent data={someDataPassedAsProp} />; }; List Virtualization in React Applications Most React applications that showcase long lists get performance issues. The application renders the entire list in the DOM before getting loaded completely. It affects the performance to a certain extent. One excellent way to deal with issues is Windowing. It allows you to render only certain items on the DOM. You do not need to render the entire list of components on your application’s screen. It will improve the performance naturally. You can enable windowing using React-window or React-virtualized. Both libraries allow you to render subcategories of the extensive list on the application screen. Lazy Loading Images A React application with numerous images loads slowly. All the images are rendered on the DOM before they are available on the screen. Thankfully, you can counter this issue using Lazy Loading Images. This technique allows images to wait until it is their turn to appear on the screen. Therefore, images do not create redundant DOM nodes. Users can use React-lazyload or React-lazy-load-image-component. These two libraries are popularly used to boost React application performance. Key Coordination for List Rendering If you’re working with lists in React, assign key attributes to elements. It will render the upcoming items on the list. By assigning a key value to components you can avoid the bottleneck issue. Use Key= { } for your dynamic lists to enhance the performance of the React app. Implementation of PureComponent Another promising way to boost the React performance is the execution of PureComponent. Use PureComponent instead of Component. It compares props and states to decide whether or not a component should be updated. import React, { PureComponent } from 'react'; class MyComponent extends PureComponent { // Component logic } Do Not Define the Inline Function Sometimes, defining functions inside the render method becomes the culprit of poor performance. What you can do is define functions outside the render method. Apart from this, you may try using arrow functions for short event handlers. See the following example: class MyComponent extends React.Component { handleClick = () => { // Handle click } render() { return <button onClick={this.handleClick}>Click me</button>; } } Use Code Splitting Another practical thing you can try to optimize the speed of a React application is code splitting. It lets you split your app into small chunks. Code splitting loads the codes required for certain features only. It automatically minimizes the initial load time. import React, { lazy, Suspense } from 'react'; const LazyComponent = lazy(() => import('./LazyComponent')); function MyComponent() { return ( <Suspense fallback={<div>Loading…</div>}> <LazyComponent /> </Suspense> ); } Use a Function in setState Do not use an object in the setState function. Instead, use a function. It is because state changes are not suggested immediately as transferred by React docs. Therefore, instead of this: this.setState({correctData: !this.state.correctData});, use the following. this.setState((prevState, props) => { return {correctData: !prevState.correctData}); } Trim JavaScript Bundles Users who want to remove code redundancy specifically can trim their JavaScript packages. Eliminate all the duplicate and irrelevant codes. It will enhance your application’s performance several times. Analyze and determine bundled code. Conclusion Undoubtedly, React is an excellent JavaScript library that helps you create user interfaces based on components. As a result, several renowned companies, including LinkedIn, DropBox, etc., use it for their applications. However, it renders numerous irrelevant components causing performance-related issues. In this post, we listed some techniques you can use to fix these issues without compromising the quality. Try these React optimization methods to make your application more responsive and user-friendly.
