+/**
+ * TJavascript class file. Javascript utilties, converts basic PHP types into
+ * appropriate javascript types.
+ *
+ * Example:
+ * <code>
+ * $options['onLoading'] = "doit";
+ * $options['onComplete'] = "more";
+ * $js = new TJavascriptSerializer($options);
+ * echo $js->toMap();
+ * //expects the following javascript code
+ * // {'onLoading':'doit','onComplete':'more'}
+ * </code>
+ *
+ * For higher complexity data structures use TJSON to serialize and unserialize.
+ *
+ * Namespace: System.Web.UI
+ *
