How To Run Javascript In Windows 10

by

JavaScript is an essential programming language for web development. It can be used for various purposes such as
altering the content of a webpage, validating user inputs, and handling user events. Running JavaScript in
Windows 10 can be done in multiple ways, and in this blog post, we will discuss three of them.

Running JavaScript in a Web Browser

All modern web browsers have built-in support for JavaScript. You can quickly test and run your JavaScript codes
within the browser without needing any additional tools or software. To run JavaScript code in a browser, follow
these steps:

  1. Create an HTML file (for example, index.html) using your favorite text editor.
  2. Add your JavaScript code either inline or as an external script.
  3. Open the HTML file in your browser to see the results of your JavaScript code.

Here’s an example of an HTML file containing inline JavaScript code: 

<!DOCTYPE html>
<html>
<head>
    <title>Running JavaScript in a Browser</title>
</head>
<body>

    <h1 id="demo"></h1>

    <script>
        document.getElementById("demo").innerHTML = "Hello, JavaScript!";
    </script>

</body>
</html>

Alternatively, you can save your JavaScript code in a separate file (for example, script.js) and
link it to the HTML file using the <script> tag, like this: 

<!DOCTYPE html>
<html>
<head>
    <title>Running JavaScript in a Browser</title>
</head>
<body>

    <h1 id="demo"></h1>

    <script src="script.js"></script>

</body>
</html>

Running JavaScript using Node.js

Node.js is a popular runtime environment that allows you to run JavaScript outside of a web browser. It is
particularly useful in running server-side JavaScript applications. To run JavaScript using Node.js, follow
these steps:

  1. Download and install Node.js from the official
    website    .
  2. Create a JavaScript file (for example, app.js) using your favorite text editor.
  3. Open the command prompt or terminal, navigate to the folder containing the JavaScript file, and execute the
    following command: node app.js.

Here’s an example of a simple JavaScript file that can be run using Node.js: 

console.log("Hello, JavaScript!");

To run this file, save it as app.js and run the following command in your command prompt or
terminal: 

node app.js

Running JavaScript using Visual Studio Code

Visual Studio Code (VSCode) is a powerful code editor that has built-in support for JavaScript and TypeScript.
You can quickly run and debug your JavaScript code using VSCode by following these steps:

  1. Download and install Visual Studio Code from the official website.
  2. Open your JavaScript file or project in VSCode.
  3. Press Ctrl + ` to open the integrated terminal.
  4. Type the following command to run your JavaScript file using Node.js: node your-file-name.js.

To run and debug your JavaScript code using breakpoints, you can also use the built-in debugger in VSCode.
Simply click on the “Run” menu, then click “Start Debugging.” The debugger will automatically run your
JavaScript code using Node.js or the browser, depending on your project configuration.

In conclusion, running JavaScript in Windows 10 is straightforward and can be done using various methods, such
as in a web browser, using Node.js, or with Visual Studio Code. Choose the method that best suits your
development needs, and start writing your JavaScript code today!
