Libraries

10. jQuery

jQuery is a lightweight, fast and cross-platform library that is used for the DOM (Document Object Model) manipulation, for the front-end processes. It is used 3 to 4 times more than any other JavaScript library. It helps the developers with its feature of adding plug-ins, creating animations, and navigating documents. Companies like Google, MSN, and DailyMotion use jQuery to build their client-side application. It creates dynamic web pages. It is so extensible and versatile, also you “write less, do more” using jQuery.

Its features are:

• AJAX
• HTML, CSS, and DOM manipulation
• Event Handling
• Excellent API and cross-browser support

11. Webpack

Webpack, a module bundler, is a tool that helps you in compiling JavaScript modules. It compresses a large number of files into a single one and runs the application. It is of great help to the DevOps team giving them the way to organize their deployment files. It loads modules with dependencies like .css, .js, .jpg and .sass into the browser. It creates excellent web applications while managing JavaScript files. Its main purpose is to bundle JS files and is capable of transforming, bundling, or packaging. 

Its features are:

• Splits Code
• Modular Plugin System
• Bundling
• Resolves dependencies 
• Opt8mizations 

12. Mocha

Mocha is an open-source JavaScript test framework that is used for testing test cases asynchronously. It allows developers to track and report on the ongoing function. It runs automated tests in NodeJS. Unlike any other, Mocha can be used with third-party assertions and spying tools. It helps in creating descriptive auto-test and reports. It has great support for both Test-Driven Development (TDD) and Behaviour-Driven Development (BDD). 

Its features are:

• Asynchronous testing
• Auto-detects
• Meta-generate suites
• Supports multiple browsers

13. NPM

Npm is the Node Package Manager for the JS platform. It is also an online repo where you can publish projects. Approximately 11 million developers use npm across the world. You can also find thousands of reusable code packages. It works with two tasks: default and arbitrary. It has greater plugins and packages. It functions in two ways – an online platform and CLI, using the online platform developers can share and upload tools, and using CLI, developers can have interactions like managing versions, installing packages, and managing the dependent tools. 

Its features are:

• Share code with npm users
• Run packages without downloading
• Collaborative Environment
• Less debugging issues
• Cross-platform projects

14. ESLint

ESLint is a tool that is used to identify and report patterns found in ECMAScript to make the code more consistent and avoid bugs. Companies like Netflix, Google, Atlassian, Microsoft, and Domain have already used it for the application. It supports Windows, Mac, and Linux. The best thing is that it can be configured according to the developer’s needs. Here “lint” refers to examining the code for errors. You should have NodeJS installed in your system to use ESLint. The command to install it is “npm install eslint –save-dev”

Its features are:

• Available as an extension of VS Code 
• A tool for pluggable JS linting
• Maintains code integrity
• Code Supervision

15. Socket.io

Socket.io is an event-driven JS library for real-time web applications. enables a low-latency and bidirectional communication for all platforms. It consists of a JS client library for the browser and a Nodejs server. It is an event-based communication between the client and server. It is Socket.io can be installed using npm using the command “npm install socket.io”. 

Its features are:

• Reliable and Scalable
• Cross-Browser Support
• Detects disconnection
• Asynchronous I/O

It’s true to say that JavaScript rules the world in the field of web development. According to GitHub, it is the most popular programming language in the world. As per the latest reports, more than 97% of the websites use JavaScript on the client side.  There are more than 15 million software developers who use JavaScript.

JavaScript is embedded with various tools which enhance the working of the application. These JavaScript tools can be IDEs, Frameworks, and Libraries. Let’s get a basic idea about these tools. 

• IDEs – It is a platform where developers implement code to create applications. You can edit code, debug it and work on commands using integrated CLI. For Example VS Code, Eclipse, and Atom. 
• Frameworks – They are used to build applications, and act as a structure to hold applications. Code redundancy can be avoided using the framework. It can also include programs, libraries, and APIs. For Example: React, Angular, and Vue.
• Libraries – It is a collection of functions to perform an operation that can be used for quick implementation. For Example mocha, socket.io, webpack, and npm.  

In this blog, we will discuss 15 must-have JavaScript Tools for Developers. So let’s get started.
