Recently I wrote a blog post and even created an online course on ES6/ES2015. Guess what? TC39—the mighty overseer of JavaScript—is moving forward with ES8 so let’s cover ES7 and ES8 (or ES2016 and ES2017 officially). Luckily, they are much, much, much smaller than the best of a standard that was ES6. Really! ES7 has only two (2) features!
ES7 features:
Array.prototype.includes- Exponentiation Operator
ES8 is not finalized yet as of this writing (Jan, 2017) but we can assume all finished proposals (stage 4) and most of stage 3 (more on stages here and in my course). The finished 2017 (ES8) proposals are:
Object.values/Object.entries- String padding
Object.getOwnPropertyDescriptors- Trailing commas in function parameter lists and calls
- Async Functions
I won’t include stage 3 proposals in this post, but you can check the status of proposals from stage 1 to 3 here.
Let’s dive deeper into the proposals and features…
