Awaiting a void function in javascript

Hi I was wondering how I could await a void function.
I tried the following (mock up):

async function asyncer() {
  setTimeout(() => {
    console.log("async msg")
  }, 0)
}

async function helloer() {
  await asyncer()
  console.log("hello")
}

helloer()

This however doesn’t work, so I tried the following :

async function asyncer() {
  setTimeout(() => {
    console.log("async msg")
  }, 0)
  return true
}

async function helloer() {
  let ready = await asyncer()
  if (ready) {
    console.log("hello")
  }
}

helloer()

Still "hello" is still logged before "async msg".
Does anyone know a solution to this problem.
Thanks in advance.

>Solution :

async/await is a syntax sugar for promise.then, so create a Promise.resolve or smth to enter in async flow and then use async/await
