What is Promise.race in Node.js?

Can you explain what Promise.race does in Node.js?

Sure! Promise.race is a method that takes an iterable of promises and returns a single promise that resolves or rejects as soon as one of the promises in the iterable resolves or rejects.

How is it different from Promise.all?

The main difference is that Promise.all waits for all promises to resolve or for any to reject, while Promise.race resolves as soon as one promise settles.

Can you give me an example of using Promise.race?

Absolutely! Here's a simple example:

const promise1 = new Promise((resolve, reject) => setTimeout(resolve, 100, 'First!'));
const promise2 = new Promise((resolve, reject) => setTimeout(reject, 200, 'Second!'));

Promise.race([promise1, promise2])
  .then(value => console.log(value)) // Outputs: 'First!'
  .catch(error => console.log(error));
