    Running JavaScript files in Visual Studio Code (VSCode) is straightforward and can be done using several methods. Here’s a step-by-step guide to help you get started.

    Using Node.js in the Integrated Terminal

    • Install Node.js: Ensure that Node.js is installed on your machine. You can download it from the official Node.js website.

    • Open VSCode: Launch Visual Studio Code.

    • Open the JavaScript File: Open the JavaScript file you want to run. For example, index.js with the following content:

    function factorial(num) {
    if (num === 0 || num === 1) {
    return num;
    }
    return num * factorial(num - 1);
    }
    let n = factorial(8);
    console.log(n); // 40320
    Copied!

    • Open the Integrated Terminal: Go to View > Terminal to open the integrated terminal in VSCode.

    • Run the JavaScript File: In the terminal, type the following command and press Enter:

    node index.js
    Copied!

    Using the Code Runner Extension
