# Debounce and throttle event handlers
High-frequency events fire hundreds of times per second, causing UI jank, excessive API calls, and poor Interaction to Next Paint (INP) scores.
## Quick Reference
- Debounce: delays execution until activity stops (search inputs, form validation)
- Throttle: limits execution rate (scroll, resize handlers)
- Use 150-300ms delay for user input, 100ms for scroll/resize
- Clean up event listeners to prevent memory leaks
## Check
Review this JavaScript code for scroll, resize, input, mousemove, or other high-frequency event handlers that should use debounce or throttle.
