    To link a JavaScript file to an HTML file, you use the <script> tag with the src attribute. This allows you to include external JavaScript files in your HTML document.

    Example

    <!DOCTYPE html>
    <html>
    <head>
    <title>Link JavaScript File</title>
    </head>
    <body>
    <h1>Welcome to My Website</h1>
    <button onclick="changeText()">Click Me</button>

    <!-- Link to external JavaScript file -->
    <script src="script.js"></script>
    </body>
    </html>
    Copied!

    In this example, the script.js file is linked to the HTML document using the <script> tag with the src attribute.

    Using ECMAScript Modules

    You can also link JavaScript files using ECMAScript modules. This approach allows you to use the import statement to include functions or variables from other JavaScript files.

    Example

    <!DOCTYPE html>
    <html>
    <head>
    <title>Link JavaScript using ECMAScript Modules</title>
    </head>
    <body>
    <script type="module">
    import { initialize } from './script.js';
    initialize();
    </script>
    </body>
    </html>
    Copied!
