JavaScript Promises

JavaScript promises act like real-life promises. The code says "I promise to get this data," and while it fetches the data in the background, the rest of the program keeps running. The promise eventually finishes and returns either the data or an error.

1/* this creates a promise */
2let myPromise = new Promise(function(resolve, reject) {
3  resolve("Data fetched!");
4});
5
6myPromise.then(result => console.log(result));
