Pretty good. Took me a minute to think through.

How do you make measurements like that? I am a noob but try to think about the efficiency of my code and wonder about ways I could check.

Very cool.

I don't think they are ranked in any order on the solutions page other than what people upvote. Most of the time, the slickest answer is upvoted for best practice and cleverness even if it is not optimal.

At first I did, but I think there are a couple tricks that make it worthy of a 5. Or 6.

Me too, always.

Good kata!

I had fun with this one. It made me realize how much I needed to strengthen my bit game.

Very clever terniary imo

Good solution in my opinion. Slick use of terniary operator and much faster than many other solutions on here :)

I really like this answer. Very clean.

Thank you. I had not seen String.prototype.someFunction before and I was confused about how to access the input string :)
