Await top level promise

1

Hello,

For a Node/Bun script I need to await the top level promise:

let yow = async () => {
 	Console.log("doing promise stuff") 
}

yow()->Promise.done

compiles to

async function yow() {
  console.log("doing promise stuff");
}

yow();

but I would need this to be await yow(); for Bun to wait until the promise is resolved.
How can I do this?

You can just write await at the top level and it’ll work fine in Bun at least.

Oh, ok, this only works when your promise returns unit.
Mine was returning an array of unit. Thanks!

Oh TIL! Didn’t know this was possible, had a similar situation recently

If you need to await a function that returns something, it’s common to assign it to _ to discard the return value

let _ = await promiseFn()

This will compile directly to await promiseFn(); which also works at the top level
