Add methods from a ShadowArray ADT and a BruteArrayADT
//int numItems ==> int to hold the number of Items in each underlying array
//E[] items ==> the data structure used in the BruteArray ADT
public void add(E item) {
//if the array needs to be expanded
if (numItems >= items.length) {
//create a new array that is twice as long
E[] brute = (E[])(new Object[items.length * 2]);

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 }
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();
