jvnlwn / gist:9510168

Created March 12, 2014 16:11

Fooling around with closures. Defined a function that accepts an argument and returns a function that manipulates said argument. I believe my gist is just an example of object referencing.

	function what(obj) {

	return function(str) {
	if (str) {
	console.log('name WAS: ', obj.name)
	obj.name = str;
	}

	console.log('name is: ', obj.name)
	}

jvnlwn / listener event confusion

Created October 27, 2013 02:34

Working on chess.js and ran into an issue when working with Backbone.js listener events inside of views. For my app, every time a chess piece is captured, it is destroyed, added to another collection for captured pieces, and a listener in the view will remove itself when its model is destroyed. When a pawn is promoted, I decided I would destroy …

	PieceView = Backbone.View.extend({

	initialize: function(options) {
	this.options = options;

	$('.chess-board').append(this.$el);

	var that = this;

	this.listenTo(this.model, 'destroy', function() {

	function arraySum(i) {

	// i will be an array, containing integers, strings and/or arrays like itself.
	// Sum all the integers you find, anywhere in the nest of arrays.
	var total = 0;

	blah(i)
	function blah(newArray) {
	array = newArray.slice()
	newArray = [];
