Here is my code:-

Answer 1

We can also use console.time() and console.timeEnd() method for the same thing.

Syntax:

console.time(label);
console.timeEnd(label);

Label: The name to give the new timer. This will identify the timer; use the same name when calling console.timeEnd() to stop the timer and get the time output to the console.

let promise = new Promise((resolve, reject) => setTimeout(resolve, 400, 'resolved'));

// Start Timer
console.time('x');

promise.then((result) => {
  console.log(result);

  // End Timer
  console.timeEnd('x');
});
