Understanding ECMAScript 6: Class and Inheritance

I’d like to share with you a series of articles about ECMAScript 6 , sharing my passion for it and explaining how it can work for you. I hope you enjoy reading them as much as I did writing them. First, I work in Microsoft on the browser rendering engine for Project Spartan, which is a vast improvement over the Internet Explorer engine we got to know (and love?) over the years. My personal favorite feature of it is that it supports a lot of ECMAScript 6. To me, this is a massive benefit to writing large applications for the web. We now have almost 70% of ECMAScript 6 features in Project Spartan so far according to http://kangax.github.io/compat-table/es6/and ES6 on status.modern.IE.
