Lesson 3.3 - Events

Event Handlers

• Event handlers are JavaScript functions that respond to events, making web pages interactive.
• It’s similar to a doorbell ringing when someone's at the door.

Common Events:

• Click Events: Clicking a button with the mouse.
• Key Press Events: Typing on a keyboard.
• Mouse Over Events: Hovering over an element.
• Form Submission Events: Submitting a form.

.addEventListener Method

• .addEventListener is the preferred way for adding event listeners in JS. It keeps JS separate from HTML for cleaner code.
• Allows you to add multiple listeners to a single event.

Example:

element.addEventListener('click', function() { 
    alert('Hello, World!');
});
