How to add JavaScript to html

To add JavaScript code to an HTML document, you can use the <script> tag. Here’s how you can do it:

Open your HTML document in a text editor or an HTML editor.
Decide where you want to insert the JavaScript code within the HTML document. Typically, it’s placed inside the <head> section or just before the closing </body> tag.
To insert the JavaScript code inside the <head> section, add the following code:

HTML

<head>
    <script>
        // JavaScript code goes here
    </script>
</head>

To insert the JavaScript code just before the closing </body> tag, add the following code:

HTML

<body>
    <!-- HTML content goes here -->

    <script>
        // JavaScript code goes here
    </script>
</body>

Replace the // JavaScript code goes here comment with your actual JavaScript code.
Save the HTML document.
Open the HTML document in a web browser to see the JavaScript code in action.

You can also include external JavaScript files in your HTML document using the <script> tag with the src attribute. For example:

HTML

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

In this case, the JavaScript code is stored in a separate file called “script.js” in the same directory as the HTML file.
