+### Promise
+
+The Promise object represents the eventual completion (or failure) of an asynchronous operation, and its resulting value.
+A Promise can be in one of these states: pending(initial state, neither fulfilled nor rejected), fulfilled(operation completed successfully), rejected(operation failed).
