Prashant Mishra on Instagram: "Attaching 100 event listeners for 100 buttons? That works… but it’s not scalable. Event Delegation is a smarter approach. Instead of adding a listener to every child element, attach one listener to the parent and use event.target to detect which element was clicked. Less memory usage. Cleaner code. Better performance. This is a common JavaScript interview question — and understanding it deeply also helps you grasp how React handles events internally. Save this for

Prashant Mishra on Instagram: "When you click a button inside nested elements, the event doesn’t just stay there. It travels. Event propagation defines the order in which elements receive that event — from top to bottom (capturing), then the target, and back up (bubbling). By default, JavaScript listens during the bubbling phase. But understanding all three phases helps you write cleaner code and avoid unexpected behavior.
