Pattern: await in Promise method arguments

Issue: -

Description

Using await on promises passed to Promise.all(), Promise.allSettled(), Promise.any(), or Promise.race() is likely a mistake as it defeats the purpose of these methods which are designed to handle multiple promises concurrently.

Examples

Example of incorrect code:

async function foo() {
  Promise.all([await promise, anotherPromise]);
  Promise.allSettled([await promise, anotherPromise]);
  Promise.any([await promise, anotherPromise]);
  Promise.race([await promise, anotherPromise]);
}

Example of correct code:

async function foo() {
  Promise.all([promise, anotherPromise]);
  Promise.allSettled([promise, anotherPromise]);
  Promise.any([promise, anotherPromise]);
  Promise.race([promise, anotherPromise]);
}
