1.1 ES6 Tutorial

Category ES6 Tutorial

Introduction

ES6, full name ECMAScript 6.0, is the next version standard of JavaScript, released in June 2015.

ES6 is mainly designed to address the inherent shortcomings of ES5, such as the lack of a class concept in JavaScript. However, the JavaScript currently used in browsers is version ES5, and most high-version browsers also support ES6, but only implement some features and functions of ES6.

Background of ECMAScript

JavaScript is the name of the language that everyone knows, but this language name is a trademark (a trademark registered by Oracle Corporation). Therefore, the official name of JavaScript is ECMAScript. In November 1996, the creator of JavaScript, Netscape, submitted JS to the international standard organization ECMA (European Computer Manufacturers Association), hoping that this language could become an international standard. Subsequently, ECMA issued a standard that specifies the browser scripting language, namely ECMAScript. This is also conducive to the openness and neutrality of this language.


The History of ECMAScript

ES6 is the most significant change in the ECMAScript standard in more than ten years, adding many new syntactic features.


The Goals and Vision of ES6

The goal of becoming a better language for writing development is as follows.

Adapt to more complex applications; achieve sharing between code libraries; continuously iterate and maintain new versions.
