Hey thanks for that, that's awesome!

One nice thing about the regex way is that it targets the letters it needs to capitalize. I added test cases for an already capitalized sentence and toTitleCase gets a 400% speedup compared to the non-capitalized sentence (since it won't call toUpperCase if it doesn't need to). The others didn't get any speed up (their code could be tweaked, but I don't think there's a way to get such a boost).
