In this episode, we have a nice and long talk with Andy Wingo (@andywingo) about the new features found in JavaScript ES6 (or ES2015, as they call it now). Andy has been (and still is) a key contributor to open source js engines like SpiderMonkey for Firefox or V8 for Google Chrome. After doing a quick travel through the strange history of this unique language, we review the big changes and new features that ES6 provides and the state of implementation on popular browsers and engines. Andy also give us some insight about how it is to contribute to open-source js engines, and finally we review some of the upcoming features in next revisions of the language.
