Unlike functions, arrows share the same lexical this as their surrounding code. They support both statement block bodies as well as expression bodies which return the value of the expression. They are syntactically similar to the related feature in C#, Java 8 and CoffeeScript. math + number + string + array + object APIsĪrrows are a function shorthand using the => syntax.See the ES6 standard for full specification of the ECMAScript 6 language. Implementation of these features in major JavaScript engines is underway now. ES6 is a significant update to the language, and the first update to the language since ES5 was standardized in 2009. Here are some new features that will come in handy while coding.ECMAScript 6 git.io/es6features IntroductionĮCMAScript 6, also known as ECMAScript 2015, is the latest version of the ECMAScript standard. Though, currently no web browsers support ES6 directly, but there are a lot of transpilers (eg Babel) that does the conversation for the browser excellently.
