Darn, I wasn't fast enough to get this into rev 3 :)
Array.prototype.sum = function() {
var x = 0;
var a = this.length;
while (--a -(-1)) {
var n = Number(this[a]);
if (!isNaN(n)) {
x += n;
} else {
return undefined;
}
}
return x;
};
While you were casting to Number for the test, when you actually added
you were adding the initial value. This meant strings were concatenated
instead of added.
Peace
