About This Episode:
Every modern web app comes alive through events—clicks, key presses, form submissions, and everything in between. In this video, we’ll dive deep into the event-driven magic that powers the browser.
Here’s what you’ll learn:
✨ Event Listeners — how to add and remove them like a pro
� The Event Object — unlock target vs currentTarget and why it matters
� Event Flow — capturing, bubbling, and how events move through the DOM
⛔ Stopping Events — when to use stopPropagation and preventDefault
� Delegation Patterns — attach one listener to rule them all (cleaner, faster code!)
Along the way, we’ll explore real-world examples like:
� Showing the mouse position in real-time
⌨️ Restricting input fields to just letters
� Preventing forms from submitting until validation passes
❌ Making “remove” buttons work with delegated events—no messy code needed
This session takes you from basic clicks ➡️ to professional event handling patterns that scale as your app grows.
