Node.js 4.0.0 arrives with ECMAScript 6 backing

Version 4.0.0 of Node.js, the popular server-side JavaScript platform also known simply as Node, arrived this week, equipped with ECMAScript 6 and ARM processor accommodations.

Proponents of Node detailed the release in a blog post on Tuesday. Accessible at the Node website and billed as a "stable" version, the release combines Node and io.js, which had been a fork of Node, into a single code base. It includes version 4.5 of the V8 JavaScript engine, which "brings with it many bonuses for Node.js users, most notably a raft of new ES6 features that are enabled by default including block scoping, classes, typed arrays -- Node's Buffer is now backed by Uint8Array -- generators, Promises, Symbols, template strings, collections (Map, Set, etc.) and, new to V8 v4.5, arrow functions," the blog said.
