+// Import data at creation
+var doa = new ObjectArray({
+	item1: 3,
+ item2: 12,
+ item3: 5
+});
+
+//Add data
+doa.push('item4', 4); // Single item or dataset
+doa.import({
+  item5: 5,
+  item6: 6
+});
+
+//Add data with dotted notations
+doa.push('dat.long.darn.key','isntIt?'); // Will automatically create each keys
+
+//Iterate on keys at root level or in sub dataset
+doa.forEach(function(value, key, index) {
+ [...]
+});
