Running JavaScript in Visual Studio Code (VS Code) is essential for modern web development to bring in interactivity.
Two main approaches for running JavaScript in VS Code are using Node.js directly in the editor and running it in a browser or using extensions for quick testing or visual feedback.
Node.js brings the V8 engine to local machines, allowing JavaScript to run outside the browser, useful for backend work, automation scripts, and quick testing without the need for an HTML shell.
To set up a JavaScript project in VS Code, install Node.js, create a project folder, initialize a basic project with npm, create a JavaScript file, and run it using 'node app.js' in the terminal. Alternatively, use the Code Runner extension for quick snippet executions.
