most readable

Really enjoy it when solutions are readable and easy to understand.

title() just capatilizes each starting letter of every new word. The dash does not count as a word; so every new letter that it encounters after the dash or any other symbol that does not represent a letter, it capitalizes.

I know, it's not the shortest answer, but I think it's the best practice, cause other people should see your code. Imagine, it's after midday, you're tired and it's easy to make stupid mistakes. And codes like this is best practise for working atmosphere. Correct me if I am wrong

I thought so too. But it seems it capitalizes each letter after a dash.
