Do I need to unsubscribe a listener to a stream that ends in Kefir?

[frankandrobot]

const oneTimeStream = Kefir.constant('foo') // this ends after firing foo
const listener = function() { //... }

oneTimeStream.onValue(listener)
// do I need to unsubscribe #listener?

Does Kefir automagically unsubscribe listeners when the stream ends or do you still need to manually unsubscribe them?

Yeah, you don't need to. All listeners automatically removed on end. Also when you subscribe to an ended stream it's a noop.

Btw, because of that you can often avoid manual unsubscribing by limiting stream with take/takeWhile/takeUntilBy/etc.

stream.take(1).onValue(fn)

Nice!
