Example : Promise All method
//Promises in ES6 - 'All' and 'Race'
let promiseOne = new Promise(function(resolve, reject) {
setTimeout(function() {
resolve('PromiseOne Resolved!');
}, 1000);
});
let promiseTwo = new Promise(function(resolve, reject) {
setTimeout(function() {
reject('promiseTwo Rejected!');
}, 2000);
});
// **All expects to get an array of promises, and combines them into one single promise**
// All will wait for all of the promises to finish, and only if ALL of them are resolved will any of them be resolved
// As soon as one single promise is rejected, no resolved values will be passed
Promise.all([promiseOne, promiseTwo])
.then(function(success) {
console.log(success);
})
.catch(function(error) {
console.log(error);
})
