I had to watch this video a few times to understand (I'm slow). But finally I get what JavaScript is actually doing to convert the capitalization. Thank you very much for the video and explanation. Much love :D

Ugh, I was struggling with this forever. FCC actually does introduce .map() before this challange, but it's a once and done thing, so I totally forgot about it. Great video! -Andy

Thank you for explaining this and introducing a new concept to me: .map()

Thanks. Really clear explanation. I should probably know this already, but why are we using square brackets [0] and curly brackets (1) in the code below?:
return word[0].toUpperCase() + word.slice(1).toLowerCase();
