We can see the order the elements are stored in memory by unrolling the array into a vector.

Passing parameterised behaviour into an algorithm (classic higher-order programming):
function proximity_sort(arr, midpoint) {
arr.sort(function(a, b) { a -= midpoint; b -= midpoint; return a*a - b*b; });
}
Simulating object oriented programming:
function counter() {
var a = 0;
