Many devs unnecessarily nest Promises like that.

    async function getData() {
      return new Promise((resolve) => {
        const res = fetch(…);
        resolve(res);
      });
    }

The response above is wrapped in THREE different Promises! One from fetch, one manually created, and one implicitly created by `async`.

The code above behaves exactly the same as

    function getData() {
       return fetch(…);
    }

or even just

    fetch(…);
