+ * We would also like to access Object.prototype.toString().
+ *
+ * The difference is this: suppose obj = new Number(7).
+ * Invoking Number.prototype.toString() on this just returns 7.
+ * Object.prototype.toString() on this returns '[object Number]'.
+ *
+ * The getJSType() function below will return '[object Number]' for us.
+ * The getJSClass() function returns 'Number', the [[Class]] property of obj.
