async await with setInterval

Question

function first(){
  console.log(\'first\')
}
function second(){
  console.log(\'second\')
}
let interval = async ()=>{
  await setInterval(first,2000)
  await set         


        

Answer 1

setInterval doesn't play well with promises because it triggers a callback multiple times, while promise resolves once.

It seems that it's setTimeout that fits the case. It should be promisified in order to be used with async..await:

async () => {
  await new Promise(resolve => setTimeout(() => resolve(first()), 2000));
  await new Promise(resolve => setTimeout(() => resolve(second()), 2000));
}
