Go didn&#x27;t invent co-routines, but the primitives of channels and the select statement that go along with them, while not ground breaking, amazingly simplify a lot of concurrency patterns that can get overly bloated and&#x2F;or difficult to reason about in other languages.<p>I have simply never seen another language that makes it as easy as Go does to reason about parallelism&#x2F;concurrency (maybe Erlang).
