-This is superb! Thank you for joining me for `JavaScript ES6-ECMAScript 6-ECMAScript 2015 Features for everyone`. I hope you will start checking/testing and incorporating these features into your code right away. I hope now you have a solid understanding of ES6 new features. Your next step could be looking into [ES7 standards/features](http://kangax.github.io/compat-table/es2016plus/) which is very new and not purely tested.
