Best Practice? Later on, I'll need to do a check on 'features' to see if a member exists: var alex = new Character(); if (alex.features['awesome']) { //do something } else if (alex.features['job']) { //not a member }

character_not_proto.js

var Character = function() {
	this.char_name  = 'Alex';
	this.char_level = 1;
	this.char_race  = 'Human';
	this.features = {
		'field of study' : 'Computer Science',
		'awesome'        : true;
	};
	
	this.health = new HpSpace();
}

character_prototype.js

var Character = function() {}

Character.prototype = {
	char_name  : 'Alex',
	char_level : 1,
	char_race  : 'Human'
	features   : {
		'field of study' : 'Computer Science',
		'awesome'        : true
	},
	
	health : new HpSpace() //function defined somewhere else
}
