How to write loops for promise with JavaScript?

To write loops for promise with JavaScript, we use async and await.

For instance, we write

const myFunction = async () => {
  //...
  while (condition) {
    const res = await db.getUser(email);
    logger.log(res);
  }
};

to use a while loop in the myFunction function.

In it, we use await to wait for the promise to resolve and return the value before we move to the next iteration.
