How to execute promises both serially and in parallel

index.js

const wait = async (time) => {
  console.log(`Going to be waiting for ${time} seconds`)
  return new Promise((resolve) => {
    setTimeout(() => {
      console.log(`Done waiting for ${time} seconds!`)
      resolve()
    }, time * 1000)
  })
}

const testsWaits = async () => {
  await wait(2)
  await wait(3)
}

const testParallel = async () => {
  const promises = [wait(2), wait(3)]
  await Promise.all(promises)
}

const testSerial = async () => {
  const times = [2, 3]
  for (time of times) {
    await wait(time)
  }
}

const testForEach = async () => {
  const times = [2, 3]
  times.forEach(async (time) => {
    await wait(time)
  })
}

//testsWaits()
//testParallel()
//testSerial()
testForEach()
