JS for Web Development

Alert Popups

Alert popups are surprisingly simple. It only takes one line of JavaScript: alert()

Three Ways to Trigger JavaScript from Buttons

1. Direct onclick (one-liner only)

This method is great for quick actions, but not ideal for complex code.

2. onclick with a Function

Organizing code in named functions improves readability and reusability.

3. Using addEventListener

This approach is preferred in modern web development—powerful and flexible!
