I always rely on bluebird each / all to loop over an array. Until someday I meet the case where I need to use await loop over an object. Surprisingly, after trying on chrome inspector, for loop on object is very doable :

const delayed = (v) => {
  return new Promise((res) => {
    setTimeout(() => {
      res(v)
    }, 1000)
  })
}
const test = async () => {
  const k = { a: 'Happy', b: 'New', c: 'Year!' }
  for (let i in k) {
    let text = await delayed(k[i])
    console.log(text)
  }
  console.log('DONE!')
}
test ()

Above codes will print a text on variable k with delay every 1 second.
