takeWhile

Takes values while the predicate is true.

Signature

takeWhile(predicate: (value: T, index: number) => boolean, inclusive?: boolean): MonoTypeOperatorFunction

What it does

Passes values through while the predicate returns true. On the first false it completes the stream; inclusive can include that last value.

When to use

Reading a stream up to a stop condition: progress < 100, status not final, values within an allowed range.
