promise/no-return-in-finally Nursery

What it does

Disallow return statements in a finally() callback of a promise.

Why is this bad?

Disallow return statements inside a callback passed to finally(), since nothing would consume what's returned.

Examples

Examples of incorrect code for this rule:

myPromise.finally(function(val) {
  return val;
});

Examples of correct code for this rule:

Promise.resolve(1).finally(() => {
  console.log(2);
});
