Promise.all() with async and await to run in console

Comment

// First promise returns an array after a delay
const getUsers = () => {
  return new Promise((resolve, reject) => {
    return setTimeout(
      () => resolve([{ id: 'ranjeet' }, { id: 'adil' }, { id: 'preet' }]),
      600
    )
  })
}


// Second promise relies on the result of first promise
const getIdFromUser = (user) => {
  return new Promise((resolve, reject) => {
    return setTimeout(() => resolve(user.id), 500)
  })
}


// Third promise relies on the result of the second promise
const capitalizeIds = (id) => {
  return new Promise((resolve, reject) => {
    return setTimeout(() => resolve(id.toUpperCase()), 200)
  })
}

const runAsyncFunctions = async () => {
  const users = await getUsers()

  Promise.all(
    users.map(async (user) => {
      const userId = await getIdFromUser(user)
      console.log(userId)

      const capitalizedId = await capitalizeIds(userId)
      console.log(capitalizedId)
    })
  )

  console.log(users)
}
