Expressive ES6 features that shine in Node.js 4.0
The developers behind Node.js released version 4.0 last week. The new version is a major update that includes significant improvements and many new language features. It is the first release to incorporate improvements from io.js, a community-driven fork that recently reintegrated with upstream Node.js.
The io.js project emerged earlier this year when prominent Node.js contributors decided to go their own way, seeking more open governance and a more predictable release cycle. They recently resolved their differences with Joyent, the corporate steward of the Node.js project. Following the reconciliation, the upstream maintainers adopted the io.js code base.
