Hasn't that been like that since rxjs 6, for more than a year? I have been using this for a loooong time. Don't get me wrong, its awesome, and more blog posts about rxjs is good. I was just expecting something new. Also I never heard about pointfree before, only about pipe and pipeable.

Good luck :)

Sure, pointfree style has been present in RxJS since version 6 but on a different level. The article is about using `pipe` for composing functions that you pass as arguments to RxJS opertators. RxJS's `pipe` is about composing the operators themselves.

RxJS's pipe: `stream$.pipe(map(x => something), filter(x => something)`

The article: `stream$.pipe(map(pipe(something, somethingElse))`
