Setup

let lastInline = 0;
let DELAY = 250;

const work = function() {
}

const throttle = function(delay, callback, schedule) {
  let last = 0;
  let handle = undefined;
  const fn = () => {
    // Cancel any scheduled invocation.
    if (handle) {
      clearTimeout(handle);
      handle = undefined;    	
    }

    const now = performance.now();
    if (now > last + delay) {
      // Invoke the callback now if enough time has passed.
      last = now;
      callback();
    } else if(schedule) {
      // Otherwise schedule it to be invoked as soon as possible when the delay expires.
      handle = setTimeout(() => fn(), delay - (now - last));
    }
  };
  return fn;
}

const throttleWork = throttle(DELAY, () => work(), false);

const throttleWorkWithSchedule = throttle(DELAY, () => work(), true);
