I liked this one, but I think for some can be a bit hard to understand.

гениально

The argument isn't being assigned to a function. The function name required by the kata (stringToNumber) is being assigned to an existing function. This is similar:
var rand = Math.random

now you have a function, rand, that can do the same thing Math.random can.

божественно

Woah that's cool. I didn't know argument could be asigned to a function and the function would be performed on it.

oooohh, now i understand. thank you!

i don't understand, how does this work?

Game over!
