In this video training you'll learn how to use promise in JavaScript.
Promise definition:The Promise object represents the eventual completion (or failure) of an asynchronous operation, and its resulting value.
A promise represents the result of the asynchronous function. Promises can be used to avoid chaining callbacks. In JavaScript,
so whenever JavaScript Code Execute as Asynchronously, need to handle an operation as one of the ways would be using promises.
Promises, have been around quite a while and are defined by a spec called Promise/A+. ES6 has adopted this spec for its Promise implementation; but there are other Promise libraries out there such as Q, Bluebird, RSVP, and others that adhere to this spec and offer other features on top of it.
