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

✅ This rule is turned on by default.

💡 A suggestion is available for this rule.

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.

Examples

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]);
}
