Just a wrapper Class for LIFO, obviously Array.pop do the job standalone.

Stack (LIFO)

var Stack = (function(){
	'use strict';

	// Class private shared vars
	var place = 'kitchen';

	// Constructor
	function Stack(some){

		// Instance private vars
		var something = 'An instance private variable ' + some;
		console.log('A new instance of Stack available', something);

		// Instance public vars
		this.items = new Array();

	}

	Object.defineProperties(Stack.prototype, {
		'place': {
			enumerable: false,
			configurable: false,
			get: function(){
				return place;
			},
			set: function(data){
				place = data;
			}
		},
		'length': {
			enumerable: false,
			configurable: false,
			get: function(){
				return this.items.length
			}
		}
	})

	Stack.prototype.add = function(item){
		return this.items.push(item);
	}

	Stack.prototype.get = function(idx){
		return !idx ? this.items.pop() : this.remove(idx);
	}

	Stack.prototype.list = function(){
		return this.items;
	}

	Stack.prototype.remove = function(idx){
		return this.items.splice(idx, 1);
	}

	return Stack;

})();
