Beginner’s Guide: Running JavaScript on Your Browser

Are you new to JavaScript and wondering how to run it on your browser? Look no further, as we provide you with a beginner’s guide to running JavaScript on your browser.

What is JavaScript?

JavaScript is a scripting language used to create and control dynamic website content. It is often used for client-side scripting and can be embedded directly into HTML code.

How to run JavaScript on your browser?

Running JavaScript on your browser is a straightforward process. All modern browsers come with built-in JavaScript engines that can interpret and execute JavaScript code.

To run JavaScript on your browser, you can either:

  • Include the JavaScript code directly into an HTML file using the <script> tag.
  • Create a separate .js file and link it to your HTML file using the <script> tag.

Option 1: Include JavaScript code in an HTML file

To include JavaScript code directly in an HTML file, you need to create a <script> tag and write your JavaScript code inside it.

<html>
  <head>
    <title>My Website</title>
  </head>
  <body>
    <h1>Hello World!</h1>
    <script>
      // JavaScript code goes here
      console.log('Hello World!');
    </script>
  </body>
</html>

In the example above, the JavaScript code console.log('Hello World!'); is included inside the <script> tag, which will be executed when the HTML file is loaded on the browser.

Option 2: Create a separate .js file and link it to an HTML file

To create a separate .js file and link it to an HTML file, you need to create a new file with a .js extension and write your JavaScript code inside it. Then, link the .js file to your HTML file using the <script> tag.

Here is an example of a separate .js file:

// script.js
console.log('Hello World!');

To link the script.js file to your HTML file, you need to include the following code in your HTML file:

<html>
  <head>
    <title>My Website</title>
    <script src="script.js"></script>
  </head>
  <body>
    <h1>Hello World!</h1>
  </body>
</html>

In the example above, the <script> tag with the src attribute is used to link the script.js file to the HTML file. The JavaScript code inside the script.js file will be executed when the HTML file is loaded on the browser.

<head>
  <title>My First JavaScript Program</title>
</head>
<body>
  <script>
    console.log("Hello, world!");
  </script>
</body>
</html>

You can save this file with a .html extension and open it in your browser to see the output.
