Each promise represents the eventual completion (or failure) of an asynchronous operation, and its resulting value. The code looks like this:

const promise = new Promise((resolve, reject) => { // do something asynchronous which eventually calls either: // // resolve(someValue); // fulfilled // or // reject("failure reason"); // rejected });
