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

✅ This rule is turned on by default.

What it does

Disallow using await in Promise method parameters

Why is this bad?

Using await on promises passed as arguments to Promise.all(), Promise.allSettled(), Promise.any(), or Promise.race() is likely a mistake.

Example

Examples of incorrect code for this rule:

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

Examples of correct code for this rule:

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