Performance optimization patterns: debounce, throttle, and immediate execution

Immediate
0
Called every keystroke
Throttled (200ms)
0
Max once per 200ms
Debounced (500ms)
0
Wait 500ms after typing

Performance Patterns

Immediate:Every keystroke triggers handler. Use for simple updates.
Throttled:Handler runs at most once per interval. Use for resizing, scrolling.
Debounced:Handler runs only after a pause. Use for search, autocomplete, API calls.

Real-World Use Cases

  • ✓ Debounce: Search inputs, autocomplete, window resize final state
  • ✓ Throttle: Scroll events, mouse movement, resize events
  • ✓ Rate Limit: API calls, button clicks to prevent spam
  • ✓ Batch: Multiple operations that can be processed together
  • ✓ Queue: Sequential processing of tasks with delays
