EcmaScriptObject

Overview

The EcmaScriptObject Object is the base class for all Javascript objects. It's a property bag that supports prototyping (through the prototype property). The engine uses this to hold and store all objects, arrays and even the "global" object in JavaScript, only primitive types are nOT instances of this type (Strings, int, int64, null, undefined). When instantiating a new instance of this type, make sure it's global object matches the one used by the script engine it will be used for.
