FWIW given the conditions of the test if someone were to use setInterval I wouldn’t be that impressed. requestAnimationFrame would be way better and even more so Web Animations API. Even then the test is still hunting for a very specific answer that amounts to trivia which should be avoided in test scenarios.

That's a great point Steve. I went ahead and added a requestAnimationFrame version too! 😊
