Event Loop & Async

What is the correct order of output?

console.log("start")
setTimeout(() => console.log("timeout"), 0)
Promise.resolve().then(() => console.log("promise"))
console.log("end")

setTimeout(fn, 0) guarantees fn runs immediately after the current line.

What does this output?

async function fetchData() {
  return 42
}
const result = fetchData()
console.log(result)
