Well done! You seem to have a good grasp on algorithms and using them in problem solving
- Count values above a threshold ✅
- Write Unit Tests ✅
- Debug and Fix the Logic ✅
- Algorithm performance experiment ✅

Another possible test case is null as input.
| console.log(countVowels("Hello World")); // Output: 3 | ||
| console.log(countVowels("JavaScript")); // Output: 3 | ||
| console.log(countVowels("")); // returns 0 | ||
| console.log(countVowels("AEIOU")); // Output: 5 |

This is a good test. Both the all vowels and uppercase get tested at the same time ⭐

A more descriptive name might be better. E.g. bigArray1k
