HTML is a markup language that provides the structure and content of web pages. However, to add interactivity to your web pages, you need to use JavaScript. In this tutorial, you'll learn how to add JavaScript to HTML.
Step 1: Create an HTML file
First, create an HTML file and give it a name. For example, "index.html". Open the file using a text editor or an HTML editor.
Step 2: Add the Script tag
To add JavaScript to your HTML file, you need to use the Script tag. The Script tag is used to define a client-side script such as JavaScript.
```html
My Web Page
Hello, World!
```
In the above code, the Script tag is added to the body section of the HTML document. The script tag is used to define a client-side script such as JavaScript.
Step 3: Add Your JavaScript code
You can add your JavaScript code inside the script tag. For example, you can create a function that displays a message when a button is clicked.
```html
My Web Page
Hello, World!
```
In the above code, a button is added to the HTML document, and the onclick attribute is used to call the displayMessage() function when the button is clicked. The function displays an alert box with the message "Hello, World!".
Step 4: Add External JavaScript File
You can also add an external JavaScript file to your HTML document. To do this, create a JavaScript file with the extension ".js", and then link it to your HTML file using the Script tag.
```html
My Web Page
Hello, World!
```
In the above code, the Script tag is used to link the "myscript.js" file to the HTML document.
Keywords: HTML, JavaScript, Script tag, client-side script, function, external JavaScript file.
