12/28/2022 0 Comments You dont know js audioThe JavaScript standard is referred to officially as "ECMAScript" (abbreviated "ES"), and up until just recently has been versioned entirely by ordinal number (i.e., "5" for "5th edition"). At the time of this writing, ES6 support varies quite a bit in browsers and JS environments (like Node.js), so your mileage may vary. Warning: All code in this book assumes an ES6+ environment. ![]() Even if you think you know JS in ES5, ES6 is full of new stuff you don't know yet, so get ready! This book explores all the major themes of ES6 that you need to get up to speed on, and even gives you a glimpse of future features coming down the track that you should be aware of. There's also a variety of new organization forms and new API helpers for various data types.ĮS6 is a radical jump forward for the language. It incorporates a whole slew of new syntactic forms, some of which may take quite a bit of getting used to. Unlike ES5, ES6 is not just a modest set of new APIs added to the language. If you've already read all those titles and you feel pretty comfortable with the topics they cover, it's time we dive into the evolution of JS to explore all the changes coming not only soon but farther over the horizon.
