ECMAScript 6 is so 2015! Meet ES2016
summary
ECMAScript 2016 (ECMA-262 7th edition) actually ships only two features: the exponentiation operator (x * y) and Array.prototype.includes; exponentiation already appears in Chrome 52, Edge 14 and recent Node builds, includes is widely supported. One proposed feature is dropped, and the spec walkthrough explains the five-stage TC39 process and the two-implementation requirement. Stage‑4 items coming next year include Object.values/Object.entries, String.prototype.padStart/padEnd* and Object.getOwnPropertyDescriptors; stage‑3 proposals include SIMD, async/await and trailing function commas.
