How would I use a "functional version of ||", or a "functional of &&"? I am not familiar with functional programing but maybe a short example of .or and .and would enlighten me a bit?

I'm guessing because .and is a function it can be used to pass into any higher order function.

    var x = [true, false, true, false];
    x.reduce(and, true); // == false
    x.reduce(or, false); // == true
