Firebase findAll

gistfile1.txt

		findAll: function() {
			var sports = {};
			var sportsRef = new Firebase(FBURL + '/sports');
			sportsRef.once('value', function(snapshot) {
				sports = snapshot.val();
			});
			return sports;
		}

I should have noted that the callback based approach is often better handled without anonymous functions:

var findAll = function(done) {
    var sports = {};
    var sportsRef = new Firebase(FBURL + '/sports');
    sportsRef.once('value', function(snapshot) {
        done(snapshot.val());
    });
};

var doCrapWithSports = function(sports) {
    // Console log all the things
    console.log(sports);
}

findAll(doCrapWithSports);

Also - my first example using promises was not covering the error side of things. You can deferred.reject instead of resolve if you have an issue (or if it times out, for ex). Highly recommend covering both the success (resolve) and failure (reject) side of a promise so that you don't end up in a limbo-edge-case state.
