This article describes the new features introduced in ECMAScript version 6 (or ES6, ES2015, ES6Harmony), formerly known as "ECMA-262 ECMAScript Language Specification 2015".

This tutorial adopts a simple and practical approach through JavaScript to describe the new features in ECMAScript 2015 (ES6), ECMAScript 2016 (ES7), ECMAScript 2017(ES8) and ECMAScript 2018 (ES9).

June 11, 2026 - ES6, or ECMAScript 2015, is the 6th version of the ECMAScript programming language.

This ECMAScript specification is the first ECMAScript edition released under Ecma TC39's new yearly release cadence and open development process. A plain-text source document was built from the ECMAScript 2015 source document to serve as the base for further development entirely on GitHub.

June 18, 2021 - This ES6 tutorial helps you get started quickly with the new version of JavaScript called ECMAScript 2015, or ES6 in short.

Some of [ECMAScript 6’s] major enhancements include modules, class declarations, lexical block scoping, iterators and generators, promises for asynchronous programming, destructuring patterns, and proper tail calls.

August 10, 2022 - With the help of the new for...of loop we can iterate over arrays or other iterable objects easily. Along with the new for...of statement, ECMAScript 6 introduces two new iterable objects too, Map for key/value maps, and Set for collections of unique values that can also be primitive values and object references.

This document is available as a single page and as multiple pages. This specification is developed on GitHub with the help of the ECMAScript community.

The proto property requires native support, and was deprecated in previous ECMAScript versions. Most engines now support the property, but some do not. Also, note that only web browsers are required to implement it, as it's in Annex B.
