    Imo;

    O(N) vs O(N) - in worst case where autocomplete words are at the end of the list, runtime is same for both.

    Ω(N) vs Ω(1) - in the best case where the autocomplete words are at the start of the list, it may be worth it to stop looping when we have found 5.

    Is it? O(n) versus O(1)? Not?

    Yes, this iterates through every element of the list. I don't think the perfomance gained from returning after 5 results is worth it in this case, the algorithm is still of the same time complexity, and I think it looks cleaner this way.
