Event listeners allow JavaScript to wait for a specific action and then respond when that action happens.
Instead of writing JavaScript directly inside HTML, event listeners keep your code clean by separating structure (HTML) and behavior (JavaScript).
Using event listeners is the professional and recommended way to handle events in modern web development.
Why Use addEventListener
- Keeps JavaScript separate from HTML
- Allows multiple events on the same element
- Makes code cleaner and easier to manage
- Follows modern development standards
- Helps build scalable applications
addEventListener is the most flexible way to handle events.
This button will be used to show how an event listener works.
The addEventListener method attaches a function to an element.
Whenever the button is clicked, the function runs automatically.
This example shows that you can attach multiple event listeners to the same element.
By mastering event listeners, students gain the ability to build interactive, clean, and professional JavaScript applications.
