Your are right. A little nick pick about TypeScript and I hope that other dislike its influence to ES6/7 too: Microsoft's mastermind behind C# and TypeScript: Anders Hejlsberg was the original author of Turbo Pascal and the chief architect of Delphi. In 1996, Hejlsberg left Borland and joined Microsoft. One of his first achievements was the J++ programming language. Since 2000, he has been the lead architect of the team developing the language C#. In 2012 Hejlsberg announced his new project TypeScript—a superset of JavaScript. I sincerely hope he stays away from ES7 - I don't like his syntax preferences. (ES4/AS3 syntax was already weird as hell, and good that it failed.) ES5/JavaScript 5 was so great and lean - so refreshing coming from C++/Java/C#. TypeScript feels a bit like a Trojan horse that emerges as ES7. As the linked article says "TypeScript: Is basically ECMAScript 6 plus optional type annotations." Or the other way around, they turned the beloved ES5 to Hejlsberg's TypeScript. So don't destroy ES7.
