Does it make sense to use TypeScript or es6+Babel in Expressjs?

Question

JavaScript

I have an idea to write an application in Express + Angular2. Angular in conjunction with TypeScript. The question is, does it make sense to use ts on the back? Or es6+Babel. The node, in principle, almost completely supports es6, but for example, it swears at import / export. Who uses what in their projects?

Answer 1

The project is large and needs further -typescript support.
A small project that you will forget about in a month -es6

Answer 2

There is a point: static typing, it greatly simplifies the support of projects.
