Angular 2.0 : Does Typescript support all the features of ES6?

Typescript started by claiming that it is a superset of Javascript. Now with ES6 around the corner. Does the current typescript transpiler/compiler support all the es6 features and syntax as it is or does it deviate from es6 interms of syntax for module export/import, arrow functions, etc?

I am asking because I am trying to learn angular 2.0 but am not able to decide whether to follow typescript path or vanilla JS path.

On top of Mark's answer, I should add that TypeScript and other transpilers allow you to use several ES6 features today. I wouldn't dream of launching a public facing website built entirely using ES6 today (early 2017), because old browsers don't die easy. TypeScript removes that inhibition altogether and also adds some innovations of its own.

Regarding features, see What's new in TypeScript and the Roadmap. (There doesn't seem to be any page that directly compares ES6/ES2015 features to TypeScript though. See @alexpod's answer.)

I suggest you use TypeScript, if for nothing else, for the extra type checking. When Angular converted their code over to TypeScript, it revealed a number of bugs.

TypeScript's primary purpose is not to add features to JavaScript – as is the purpose of ES2015 – but to make it easier and safer for developers to write and maintain large JavaScript applications. The primary benefit of TypeScript shows up before your application runs – when you're writing or maintaining code. Intellisense, code completion, type checking, etc.

Look at this table. It will show you what typescript and other transpilers/environments support right now.
