Implement throttle

function throttle(callback, delay) {
  let isThrottled = false;
 
  return function(...args) {
    if(!isThrottled) {
      callback.apply(this, args); // Execute the function immediately
      isThrottled = true;
 
      setTimeout(() => {
        isThrottled = false; // Reset for future calls 
      }, delay);
    }
  }
}
