By default, the execution of a Flow is sequential, since the producer and the collector code run in the same coroutine.

With the buffer operator, we can achieve concurrent flows by decoupling the producer and the emitter. This way, the producer can emit new items even before the collector fully processed the previous item. This works because the producer and the collector now run in their own coroutines.

Items that haven’t yet been processed end up in a buffer.
