Introduction to ECMAScript 6

This book contains step-by-step instructions on the use of new features of ESMAScript 6 instead of obsolete tricks and programming tricks on JavaScript.
The book begins with acquaintance with all embedded ES6 objects and describing the creation of ES6 iterators. Then she will tell how to write asynchronous code using ES6 in the usual style of synchronous code. The following describes the use of the Reflects API reflection program interface to study and change the properties of objects. Then examines the creation of proxy objects and their application to intercept and change the behavior of operations with objects. Finally, outdated modular programming methods, such as IIFE, COMMONJS, AMD and UMD, are demonstrated and compared with ES6 modules that can significantly increase the productivity of websites.
