ECMAScript 7 functionalities
Until the date that this book is being written, only one functionality is confirmed to be shipped with ES7 (or ECMAScript 2016), which is called Array.prototype.includes.
There are other functionalities that are almost ready and may be included in ES7 but still not confirmed, which are:
- The exponentiation operator
- SIMD.JS - SIMD APIs + polyfill
- Async functions
Object.values/Object.entries- String padding
- Trailing commas in function parameter lists and calls
The exponentiation operator may come in handy when working with math, and it simplifies the Math.pow(2, 3) code to 2 ** 3, where ** is designed to be the new exponentiation operator.
You will learn more about the Array.prototype.includes functionality in the next Chapter ...
