It’s June and this means that the new 11th edition of ECMA-262 standard defining the ECMAScript and thus JavaScript language will be out shortly. Now, as you might know from my previous article about ECMAScript and the one about ES2019 features, JavaScript, ever since the introduction of ES6, is experiencing kind-of a rolling release cycle. This means that while new editions of the ES specification go through the whole proposal, discussion, approval and finalization process, individual features often appear much earlier in different browsers than the yearly specification release.

With that said, it’s still a nice thing to have this moment in a year that you can say which new JS features are here for sure. And even though most web developers won’t use all those features right away due to compatibility concerns, it’s good to keep an eye on where the language is going.

And so, in this article, we’ll go over the biggest of the new features introduced with ES2020.
