How To Run Javascript In Visual Studio Code

Web Development Software

Running JavaScript in Visual Studio Code is a crucial part of my coding routine. As a developer, I’ve found that having the ability to seamlessly execute and debug JavaScript code within Visual Studio Code greatly enhances my productivity. In this article, I’ll guide you through the process of running JavaScript in Visual Studio Code, sharing personal insights and tips along the way. Let’s dive in!

Setting Up Visual Studio Code for JavaScript

First things first, if you haven’t already installed Visual Studio Code, you can download it from https://code.visualstudio.com/. Once you have Visual Studio Code up and running, you’ll want to install the essential extension for JavaScript development.

To do this, navigate to the Extensions view by clicking on the Extensions icon in the Activity Bar on the side of the window. Search for “JavaScript” in the Extensions view search box, and you should find the official JavaScript (ES6) code snippets extension by charalampos karypidis. Click the Install button to add this extension to your Visual Studio Code setup. This extension provides ES6 syntax highlighting, snippets, and code completion for JavaScript.

Creating and Running a JavaScript File

With our environment set up, it’s time to create our JavaScript file. I typically create a new folder within Visual Studio Code for each project, and then add a new file with a .js extension. To create a new JavaScript file, you can right-click on the folder in the Explorer view, select “New File,” and give it a name with the .js extension.

Next, you can start writing your JavaScript code in the newly created file. For example, you can write a simple “Hello, World!” program:


console.log('Hello, World!');

Now, to run this JavaScript file, you can open the integrated terminal in Visual Studio Code by pressing Ctrl + `. Here, you can use Node.js to execute your JavaScript file. Ensure that Node.js is installed on your system. To run the file, enter the command:


node filename.js

Debugging JavaScript in Visual Studio Code

Visual Studio Code offers powerful debugging capabilities for JavaScript. To set a breakpoint in your code, you can simply click in the area to the left of the line numbers in your JavaScript file. This will add a red dot, indicating a breakpoint, allowing you to inspect variables, step through code, and diagnose issues with ease. To start debugging, you can press F5 or click the green play button in the debugging view. This will launch the debugger and stop at your breakpoints, giving you full control over the execution flow of your JavaScript code.

Conclusion

Running JavaScript in Visual Studio Code is an indispensable aspect of my development workflow. With the seamless setup, execution, and debugging capabilities that Visual Studio Code provides, JavaScript development becomes a smooth and efficient process. I hope this guide has been helpful in getting you started with running JavaScript in Visual Studio Code. Happy coding!
