Install VS Code
The first step to setting up a Javascript development environment in VS Code is to install the editor itself.
VS Code is a free, open-source code editor created by Microsoft. It's lightweight, fast, and has a wide range of extensions available that make it perfect for Javascript development.
You can download VS Code from the official website https://code.visualstudio.com/. Once you have downloaded and installed it, you can proceed to the next step.
Install Node.js
The next step is to install Node.js, which is a Javascript runtime that allows you to run Javascript code outside of a web browser.
Node.js is essential for Javascript development, and many popular frameworks and libraries (such as React and Angular) rely on it.
You can download Node.js from the official website https://nodejs.org/. Once you have downloaded and installed it, you can proceed to the next step.
Install Extensions
One of the best things about VS Code is its extensive library of extensions.
Extensions are plugins that add functionality to VS Code. There are many extensions available that are specifically designed for Javascript development.
To install extensions, click on the Extensions icon in the left-hand sidebar of VS Code. You can then search for and install the extensions that you need.
Some popular extensions for Javascript development include ESLint, Prettier, and Debugger for Chrome.
Configure Workspace Settings
Once you have installed the necessary extensions, you can configure your workspace settings to optimize your development environment. Workspace settings are specific to your project and are stored in a .vscode folder in your project directory.
To access your workspace settings, go to File > Preferences > Settings. From there, you can configure settings such as auto-save, tab size, and line endings. You can also configure settings for specific extensions.
Debugging in VS Code
Finally, debugging is an essential part of the development process. VS Code has built-in debugging tools that allow you to debug your Javascript code with ease. You can set breakpoints, inspect variables, and step through your code line by line.
To start debugging, click on the Debug icon in the left-hand sidebar of VS Code. From there, you can create a launch.json file that specifies how to start your application and start debugging.
But...yes you can use console.logs to debug JS code 🙌 So for the sake simplicity, ignore this step for now!
Conclusion
In conclusion, setting up a Javascript development environment in VS Code is not as difficult as it may seem. By following the steps outlined in this article, you can create a powerful, efficient development environment that will help you write better Javascript code.
