# unicorn/no-await-in-promise-methods

> Disallow `await` on the elements of the array passed to `Promise.all()` and similar methods

`Promise.all([await loadUser(), await loadPosts()])` waits for the user before it starts loading the posts. The requests run one after the other, and `Promise.all()` only gets finished values, so it has nothing left to do. With `Promise.race()` and `Promise.any()`, there's no race either.

The rule checks `Promise.all()`, `Promise.allSettled()`, `Promise.any()`, and `Promise.race()`.

`--fix-suggestions` removes the `await`.
