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

How does this timing pattern differ from debouncing?

function throttle(fn, delay) {
  let lastCall = 0;
  return function(...args) {
    const now = performance.now();
    if (now - lastCall >= delay) {
      fn.apply(this, args);
      lastCall = now;
    }
  };
}

It's exactly the same
It executes immediately rather than after a delay
It ensures maximum execution frequency
Throttling differs from debouncing: 1) Guarantees maximum execution frequency, 2) Executes first call immediately, 3) Useful for rate-limiting frequent events, 4) Maintains regular execution pattern, 5) Better for real-time updates like gaming, 6) Doesn't delay execution until event stream ends.
It prevents all repeated calls
