Events & Interactions

1What is JavaScript?✨

JavaScript is a dynamic programming language that makes websites interactive. It's a key technology behind web applications and is used by developers all over the world!

2Why Learn JavaScript?🎯

• ✓ Enables interactivity on web pages
• ✓ Essential for front-end development
• ✓ Powers popular websites like Facebook, Twitter, and Google
• ✓ Great for building engaging user experiences

3Your First Program💡

Every web developer adds this to their page:
console.log("Hello, World!");

This tells JavaScript to display text in the console, which is useful for debugging.

4Understanding Events🚀

Events are actions that occur in the browser, like clicks or key presses. You can use JavaScript to respond to these events and make your webpage interactive.

5Example:🔍

document.getElementById("myButton").addEventListener("click", function() {
    alert("Button was clicked!");
});

This code shows an alert when the button with the ID "myButton" is clicked.

6Creating Interactions⭐

You can respond to different types of events. Here are some common ones:
- Click events (mouse clicks)
- Key events (keyboard presses)
- Mouse events (hovering over elements)

7Example:🧩

document.addEventListener("keypress", function(event) {
    console.log("Key pressed: " + event.key);
});

This code logs the key that was pressed to the console.
