I suggest reading the ExploringJS books [0]. If you already know ES5 then you can jump to Exploring ES6 [1], then you can work your way through Exploring ES2016 and ES2017, and finally Exploring ES2018 and ES2019. Each book explains what new features that were added to the language as part of that specific version. Don't feel daunted though! ES6 added the largest amount of features, and after that there haven't been nearly as many changes. If you find the book useful please consider buying a copy; I'm not associated with the author in any way, just a big fan of his writings.
