function throttle(fn, limit) {
  let inThrottle;
  return function(...args) {
    if (!inThrottle) {
      fn.apply(this, args);
      inThrottle = true;
      setTimeout(() => inThrottle = false, limit);
    }
  };
}

Throttling enforces a maximum execution rate, ensuring the function fires at most once per defined time interval.
