Debouncing vs. Throttling in React
Debouncing waits for a pause in events before acting; throttling fires at a steady rate. Use debounce for search bars to avoid API calls on every keystroke, and throttle for scroll handlers to prevent lag.
Debouncing and throttling control how often a function runs in response to frequent events. Debouncing waits for a pause before acting, like waiting for a user to stop typing. Throttling ensures a function runs at most once per interval, like handling scroll events every 200ms. Use debounce for search inputs to reduce API calls; use throttle for scroll/resize handlers to prevent performance drops. The main footgun is misapplication: debouncing a scroll handler is useless as it only fires after the user stops.
