Debounce & Throttle Functions

What additional functionality does this debounce implementation provide?

const debounceWithImmediate = (func, wait, immediate = false) => {
  let timeout;
  
  return function(...args) {
    const callNow = immediate && !timeout;
    
    clearTimeout(timeout);
    timeout = setTimeout(() => {
      timeout = null;
      if (!immediate) func.apply(this, args);
    }, wait);
    
    if (callNow) func.apply(this, args);
  };
};

Automatic retry on failure
Cache support
Immediate execution option on the first call
This enhanced debounce implementation adds immediate execution capability: 1) It allows for optional immediate execution on the first call, 2) The immediate parameter controls whether to execute at the start or end of the debounce period, 3) This is useful for providing immediate feedback while still debouncing subsequent calls, 4) It maintains the standard debounce behavior for follow-up calls, 5) The pattern is particularly useful for UI interactions requiring immediate response, 6) It provides more flexibility in handling different use cases, 7) The implementation properly handles both immediate and delayed execution scenarios, 8) This feature makes the debounce more versatile for various application needs.
