foo.js

const wait = time => new Promise(resolve => setTimeout(resolve, time))
const x = (...args) => {
  console.log('-----------------------------')
  console.log(...args)
}

wait(1000)
  .then(() => fetch('https://www.google.co.jp', { header: "same-origin" }))
  .then(response => response.text())
  .then(text => x('this is the response', text))
  .catch(e => console.error(e))

www.google.co.jpで実行しないとthenが呼ばれないです
