Async delay#

With simple errorhandling

function delay(time) {
  return new Promise((resolve, reject) => {
    if (isNaN(time)) retun(reject(new Error('delay requires a valid number')))
    setTimeout(resolve, time)
  })
}

Short version without errorhandling

function delay(time) {
  return new Promise((resolve, reject) => setTimeout(resolve, time))
}
