Yes, because Typescripts is 2 things:<p>* A language, superset of ES6 that adds optional types<p>* A compiler (like Babel) that will take your Typescript code, check if the types are correct, remove them, and transpile the non-ES5 parts of into ES5 (just like Babel).<p>So if you want to use Typescript-the-langage, you need Typescript-the-compiler and you will no longer need Babel.
