JS return values chain well

Make an array

var a = []
=> []

And a function that returns the array

var b = function(){ return a }
=> function (){ return a }

Invoking the function will return an array

b()
=> []

Since an Array is the return value of that function, I can chain Array methods to the function

b().push(1)
=> 1

Moreso, that method actually influenced the a array;

a
=> [1]

Think of the possibilities...
