What is Promise ?
Answer :
Promises are a tactic for deferred computing, suitable for several styles of concurrency: thread and event loop concurrency for local computation, and both synchronous and asynchronous remote messaging. A promise represents the eventual result of an asynchronous operation. The primary way of working with promises is through a method which registers callbacks to receive the promise\'s eventual value or the reason why the promise cannot be fulfilled.
