Maybe

async

should return

Coroutine

class

rrader: This is the wrong concept. Coroutine is just a background computation. Coroutine ~ Thread. While

async

returns an object also known (in computer science) as a future or a promise: https://en.wikipedia.org/wiki/Futures_and_promises

but

Deferred

also seems incorrect, because it means it will run later

Coroutine has different meaning already, it wont be good to use it two times

Deferred here is just a synonym for Promise/Future and it does mean that it is run later. That is actually what is happening — it is being run later

ok, it will run almost at the same time in Go also are

defer

Go’s

defer

is a misnomer. We cannot help that.
