JavaScript Event Delegation is a technique where a parent element handles events for its child elements using event bubbling. Instead of attaching event listeners to many child elements individually, you attach one listener to a common parent and determine which child triggered the event.
Debounce vs throttle is a core JavaScript concept used to control how often a function runs during repeated events. In frontend development, both help improve performance by preventing excessive function calls during typing, scrolling, resizing, or API requests. The key difference is simple: debounce waits, while throttle limits frequency.
