For more information, see Functions (JavaScript).
The arrow (=>) function provides you with a shorthand for the function keyword with lexical "this" binding. Promises allow easier and cleaner asynchronous coding. It is an abstraction for managing interactions with asynchronous APIs. Promises provide you with a mechanism to schedule work to be done on a value that has not yet been computed. For more information about classes, see Classes in JavaScript: Exploring the Implementation in Chakra. A class allows you to create new objects using prototype-based inheritance, constructors, instance methods, and static methods. ClassesĮS6 introduces a syntax for declaring classes. Microsoft Edge for Windows 10 extends the JavaScript enhancements of Internet Explorer 11 with new support for features from the latest ECMAScript 6 (ES6) draft specification.
