How to download javascript on your computer

With the rapid development of Internet technology, JavaScript has become a very important programming language. When we develop web pages or other software, we need to use JavaScript language. However, after we install the computer system, JavaScript is not installed by default, so how to download JavaScript on the computer? Below I will introduce how to download JavaScript on your computer.

1. Understand how to install JavaScript

Before downloading JavaScript, we need to understand how to install JavaScript. There are two main ways to install JavaScript: one is JavaScript running in the browser, which is installed with the browser by default and we do not need to download additionally; the other is an independent JavaScript interpreter, which needs to be downloaded and installed separately .

2. Download popular JavaScript interpreters

There are many popular JavaScript interpreters, such as Node.js, Rhino, SpiderMonkey, etc. Of these three interpreters, Node.js is the most popular. Node.js is a JavaScript interpreter based on the Chrome V8 JavaScript engine, which allows programming with JavaScript on the server side.

If you are interested in server-side JavaScript programming, then Node.js is the best choice for you. You can open the official website of Node.js (nodejs.org) and choose the version suitable for your computer system to download and install.

3. Download the JavaScript Integrated Development Environment (IDE)

When writing JavaScript programs, we need to use special development tools for code writing and debugging. JavaScript's integrated development environment (IDE) can provide a series of plug-ins, code editors, debuggers and other rich functions to help us better write JavaScript programs.

Below we introduce several popular JavaScript integrated development environments:

1. Visual Studio Code

Visual Studio Code is a lightweight, cross-platform A platform-based, free IDE that supports multiple programming languages, including JavaScript. It features code coloring, smart code hints, debugging, and Git integration.

The way to download Visual Studio Code is very simple. You only need to open its official website (code.visualstudio.com), and then select the version suitable for your computer system to download and install.

2. WebStorm

WebStorm is an IDE focused on web development. It supports multiple programming languages, including HTML, CSS, JavaScript and TypeScript. It features code coloring, smart code hints, code auto-completion and debugging.

WebStorm is not free, but you can download a free trial to use it. You can open the JetBrains official website (jb.com) to download the version that suits you.

4. Download JavaScript function libraries and tools

JavaScript has many excellent function libraries and tools that can help us write programs better. For example:

1. jQuery (jQuery.com) is a JavaScript library that is fast, simplified, and compatible with various browsers. It is widely used in front-end development.
2. Underscore.js (underscorejs.org) is a JavaScript function library that provides many practical functions, which is very suitable for front-end and back-end development.
3. Lodash (lodash.com) is a more modern JavaScript function library that provides more advanced functions and methods and is more powerful than Underscore.js.
4. Babel (babeljs.io) is a widely used JavaScript compiler that can convert the latest JavaScript code such as ES6, ES7 and JSX into ES5 code to run in current browsers.

Summary

It is not difficult to download JavaScript on your computer. You just need to understand its different installation methods and choose the version that suits you to download and install. We provide suggestions on downloading JavaScript interpreters, integrated development environments, and function libraries for your reference and selection. I hope this article will be helpful to you and enable you to program JavaScript more smoothly.
