I have difficulty googling what

future { }

does since instead it comes up with a ton of articles telling me that Kotlin is the future of android programming.. is this just a wrapper as a

CompletableFuture

? anyone know any link to any documentation or articles describing the use for it?

future { }

launches a coroutine (the body is a suspend function) and the result of the expression is a CompletableFuture that represents the final result/exception of the code in the body

it’s analagous to

async { }

(which returns a Deferred) or

launch { }

(which returns only a Job)

you can think of it as being kind of like CompletableFuture.supplyAsync, except you’re giving a suspendable coroutine body … if you don’t suspend, then they’re basically the same (this is a simplification)

thanks for the explanation

any help will be appreciated. thanks https://kotlinlang.slack.com/archives/C0B8H786P/p1624032117075000
