This is awesome, just need to add a check for humanYears === 0, I think.

I like this one. I don't entriely get it but I know what I like.

Arrow functions..nice

very clean <3

Also still lost with this one...

edit: oh, it's the truthy/falsy values of 0 & 1 that allow the ternary operator to work

ohh nice arrow function as well
