Debounce & Throttle Functions

What advanced feature does this throttle implementation provide through its options parameter?

function throttle(func, limit, options = {}) {
  let lastRan, timeout;
  
  return function(...args) {
    if (!lastRan && options.leading === false) {
      lastRan = Date.now();
      return;
    }
    
    const now = Date.now();
    if (!lastRan || (now - lastRan) >= limit) {
      func.apply(this, args);
      lastRan = now;
    } else if (options.trailing !== false) {
      clearTimeout(timeout);
      timeout = setTimeout(() => {
        func.apply(this, args);
        lastRan = Date.now();
      }, limit - (now - lastRan));
    }
  };
}

Control over leading and trailing edge execution
This advanced throttle implementation provides important configuration options: 1) It allows control over both leading and trailing edge execution, 2) The leading option determines if the function executes on the first call, 3) The trailing option controls whether to execute after the throttle period, 4) This flexibility makes the throttle more adaptable to different use cases, 5) Leading edge control is useful for immediate feedback scenarios, 6) Trailing edge control helps ensure final state updates aren't missed, 7) These options allow fine-tuning of throttle behavior for specific needs, 8) This implementation represents a production-ready approach to throttling.
