const task = (timer) => {
  return new Promise((resolve, reject) => {
    setTimeout(() => {
      console.log(new Date())
      resolve()
    }, timer);
  })
}

const taskRunner = async () => {
  await task(3000);
  taskRunner();
}
taskRunner();

            resolve();
        }, 3000);
    })

const time = async () => {
    await showTime();
    time();

function time() { let promise = new Promise(resolve => { setTimeout(() => { console.log(new Date()); resolve() }, 3000) }) promise.then(() => time()) }
