I took almost 40 minutes, am I in the wrong profession? I figured out how to do all of them right away but I got stuck on figuring out JS syntax in a few places since I barely ever use it and felt like googling was cheating. I did use google on the last one to see how to check if something's an array. I even ended up checking at one point if something's a number by (!isNaN(n/4) && n+n == 2*n), and checked for being a string or not with if(s.length!=undefined) (I know that returns true for an array as well). Would've been a lot easier with something like Intellisense - coding without it feels almost like I'm blind, after being used to it. That and I thought alert() didn't work until I noticed at the end it actually sent it to the output.
