setTimeout(), setInterval(), and requestAnimationFrame()

What timing pattern does this code implement?

function debounce(fn, delay) {
  let timeoutId;
  return function(...args) {
    clearTimeout(timeoutId);
    timeoutId = setTimeout(() => fn.apply(this, args), delay);
  };
}

Throttling
Debouncing
This implements debouncing: 1) Delays function execution until after a pause in calls, 2) Cancels previous timeout when function is called again, 3) Useful for handling rapid-fire events like resize or scroll, 4) Ensures function only runs once after last call in series, 5) Maintains original function context with apply(), 6) Common pattern for performance optimization.
