Thanks for pointing out the issues with sum. I think I have found a
decent solution, though I'm not certain of the performance hit.
Array.prototype.sum = function() {
var x = 0;
var a = this.length;
while (--a -(-1)) {
if (!isNaN(Number(this[a]))) {
x += this[a];
} else {
return undefined;
}
}
return x;
};

Oops! Nice catch. :)

Where? I just double-checked. The only place I can think your compiler
might complain is Array.fill, but 'len' is an argument.
