Example of running all parallel promises with a race timeout promise in javascript

promise-timeout.js

const promise1 = new Promise((resolve, reject) => {
  setTimeout(resolve, 50, 'one');
});

const promise2 = new Promise((resolve, reject) => {
  setTimeout(resolve, 60, 'two');
});

const promise3 = new Promise((resolve, reject) => {
  setTimeout(resolve, 70, 'three');
});

const timeoutPromise = new Promise((resolve, reject) => {
  setTimeout(reject, 65, 'timed out');
});

const parallelPromise = Promise.all([promise1, promise2, promise3])

Promise
.race([parallelPromise, timeoutPromise])
.then((value) => {
  console.log(value);
})
.catch((err)=>{
  console.log(err)
});
