Kris Kindle Algorithm in JS, using Google's AppScript to send emails to everyone involved

KrisKindle.js

function krisKindle() {
	"use strict";
	var peopleInKrisKindle, bag, key, giver,firstGiver, reciever, sendMail;
	sendMail = function(giver, reciever) {
		var email = peopleInKrisKindle[giver],
			subject = "Secret Santa",
			message = "You have to get a gift for " + reciever;
		MailApp.sendEmail(email, subject, message);
	};
	peopleInKrisKindle = {
		Santa: "santa@gmail.com",
		Rudolf: "rudolf@hotmail.com",
		Dasher: "dasher@hotmail.com",
		Prancer: "prancer@gmail.com"
	};//spec: keys are names, values are emails
	bag = [];
	for (key in peopleInKrisKindle) {
		if (peopleInKrisKindle.hasOwnProperty(key)) {
			bag.push(key);
		}
	}
	giver = bag.splice(Math.floor(Math.random() * bag.length), 1);
	firstGiver = giver;
	while (bag.length > 0) {
		reciever = bag.splice(Math.floor(Math.random() * bag.length), 1);
		sendMail(giver, reciever);
		giver = reciever;
	}
	sendMail(giver, firstGiver);
}

Corrected spelling. :P https://gist.github.com/JackBracken/8076201

Thanks Jack :P At least it's mis-spelled consistently so the code still works.

True dat.
