race < Promise < JavaScript

The Promise race() static method takes an iterable of promises as input and returns a single Promise. This returned promise settles with the eventual state of the first promise that settles.

    
    const promise1 = new Promise((resolve, reject) => {
      setTimeout(resolve, 500, 'one');
    });

    const promise2 = new Promise((resolve, reject) => {
      setTimeout(resolve, 100, 'two');
    });

    Promise.race([promise1, promise2]).then((value) => {
      console.log(value);
     // Both resolve, but promise2 is faster
    });
    // "two"
