Debounce & Throttle Functions

A debounce function serves a crucial performance optimization purpose: 1) It delays function execution until after a specified pause in event triggers, 2) It's particularly useful for handling rapid-fire events like window resizing or scrolling, 3) It ensures that a function only executes after the event stream has stopped for a defined period, 4) This prevents excessive function calls that could degrade performance, 5) The timeout resets each time the event fires before the delay period ends, 6) It's ideal for expensive operations that don't need to run on every event, 7) Common use cases include search input handling and window resize calculations, 8) It helps in reducing unnecessary API calls or DOM updates.
