Is TypeScript still relevant?

Question

JavaScript

Is TypeScript still relevant or is it disappearing like CoffeeScript?
After all, ES6 and Babel.js appeared.

Answer 1

I will say that apart from the goodies from Ruby, there is nothing in CoffeeScript. I never understood the people who lifted CoffeeScript to the skies.
If you take pure ES2015 - TypeScript will be better.
If you take ES2015 + Flow + some Stage2 and Stage3 props, you already need to do a headsup analysis.
For the most part, they will be similar. You need to be able to write a good assembly with these tools yourself (the necessary features from the standards, the necessary support for browsers, preprocessors, etc.).
In terms of functionality, they are roughly the same. Personally, my preference among these two (if we take charged es2015/flow/stage2/stage3) is TypeScript. Normal OOP (with access modifiers), autocomplete is more stable.
And believe me, TypeScript will live on for a very long time.

Answer 2

Typescript can do everything that is es6 and even more, it is an add-on (extension) over es6. So es6 will die soon

Answer 3

TypeScript may start to die if full-fledged native typing appears (obviously not in the near future), or everyone moves to WebAssembly or something similar (also not soon). At the moment, TypeScript is keeping up with JS, but 2 steps ahead + has an arsenal of features that are not planned to be imported into JS. Also, TS may have problems like "the developers abandoned it", but this is not related to the development of js.
