Any time you find yourself writing code like "if(x){return true} else{return false}", you can simply replace it with "return x", since x will resolve to true or false anyway. In your example the logic is reversed, but still it's basically saying "if(true){return false} else {return true}", so you could replace that with "return !x"

yes

Kata stipulates "an array with exactly 5 strings". Not great for general use, but meets the requirements of the kata.

It isn't one loop. It filters (and sorts) twice. EDIT: nevermind, I see that you're asking how one might do it in one loop.

I gotta admit, this is highly readable!

I'm afraid I don't know the under-the-hood aspects of sort as well as I'd like, but it does seem to sort numbers by default.

I also realized that it should probably be i <= 100, just for the outlier situation of having 10 arrays of 10 elements covering numbers 0-99

Nice solution! My only question is how the .sort() function is successfully sorting numerically (rather than its default - alphabetically) without a function passed to it?

What's the point of slicing? It seems to be extra overhead and less readable.

WOW

first

use === instead of ==

But then you'd have to type all those quotes and commas!!
