title: timeTaken tags: function,beginner

Measures the time taken by a function to execute.

Use console.time() and console.timeEnd() to measure the difference between the start and end times to determine how long the callback took to execute.

const timeTaken = (callback: Function) => {
  const id = `timeTaken_${Date.now()}`;
  console.time(id);
  const r = callback();
  console.timeEnd(id);
  return r;
};

timeTaken(() => Math.pow(2, 10)); // 1024, (logged): timeTaken: 0.02099609375ms
