A channel is a sender and receiver pair that allows one component to send values to another. A sender and receiver pair is similar to an AsyncPipe and AsyncGenerator pair. However, unlike AsyncPipe/AsyncGenerator, senders and receivers can be used by memory‐efficient higher level transformation abstractions.
