JavaScript is a versatile programming language used for adding interactivity to web pages. It allows you to create dynamic and responsive user experiences.

What You’ll Learn:

• What JavaScript is and how to include it in your HTML.
• Basic JavaScript concepts like variables, functions, and events.
• How to write and execute your first JavaScript code.

Step 1: Adding JavaScript to Your HTML

You can include JavaScript in your HTML file using the <script> tag. Here’s an example:

<script>
console.log("Hello, World!");
</script>

Step 2: Using External JavaScript Files

To keep your code organized, you can write JavaScript in an external file and link it to your HTML:

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

Save your JavaScript code in a file named script.js and place it in the same directory as your HTML file.

Step 3: Writing Your First JavaScript Code

Here’s a simple example that displays an alert message when the page loads:

alert("Welcome to JavaScript!");

Step 4: Working with Variables

Variables store data that you can use later. Here's an example:

let name = "John";
console.log("Hello, " + name);

Step 5: Adding Interactivity with Events

JavaScript can respond to user actions, like clicking a button:

<button onclick="sayHello()">Click Me</button>
<script>
function sayHello() {
alert("Hello, World!");
}
</script>

Step 6: Exploring More Features

Now that you know the basics, try exploring:

• Loops and conditional statements for decision-making.
• Working with arrays and objects to manage data.
• Using the DOM (Document Object Model) to manipulate HTML elements.

Happy coding!
