Description Of The Issue

The signature

range(start: number = 0, count?: number, scheduler?: SchedulerLike): Observable<number>

suggests that range(n) is equivalent to range(n, undefined), but it's actually range(0, n).

Maybe add an overload range(count: number) .

Less importantly, range(n, Infinity) emits an infinite sequence, contrary to the documentation.

Observable: An Observable of numbers that emits a finite range of sequential integers.
