JAVASCRIPTTM PROGRAMMING EXTENSION

1 . A system comprising:

a code generator to:

access an existing JavaScript™ file;

validate JavaScript™ definitions in the existing JavaScript™ file, and

generate a Java™ representation of the existing JavaScript™ file; and

a JavaScript™ reference converter to generate a validated JavaScript™ corresponding to the existing JavaScript™.

2 . The system of claim 1 , including a JavaScript™ authoring module to facilitate authoring of JavaScript™ files.

3 . The system of claim 2 , wherein the JavaScript™ authoring module comprises a JavaScript™ runtime framework to support object-oriented component programming style with JavaScript™.

4 . The system of claim 2 , wherein the JavaScript™ authoring module supports JsDoc annotation to declare data types.

5 . The system of claim 1 , wherein the Java™ representation of the existing JavaScript™ file comprises a typed referencing class in Java™ for each JavaScript™ component in the existing JavaScript™ file.

6 . The system of claim 4 , wherein the code generator is to provide value-binding support.

7 . The system of claim 1 , wherein the JavaScript™ reference converter comprises one or more converters to convert Java™ data type into JS-compatible data type.

8 . The system of claim 7 , wherein the one or more converters include a date converter to convert a Java™ Date type into a JavaScript™ compatible type.

9 . The system of claim 1 , further comprising a dependencies manager to maintain one or more dependencies among one or more JavaScript™ components in the validated JavaScript™ file.

10 . The system of claim 1 , wherein the system is integrated with an Integrated Development Environment (IDE).

11 . A method comprising:

accessing an existing JavaScript™ file;

validating JavaScript™ definitions in the existing JavaScript™ file; and

generating a Java™ representation of the existing JavaScript™ file.

12 . The method of claim 11 , wherein the Java™ representation of the existing JavaScript™ file is a Java™ class.

13 . The method of claim 11 , further comprising generating a validated JavaScript™ file corresponding to the existing JavaScript™.

14 . The method of claim 14 , further comprising obfuscating the contents of the validated JavaScript™ file module to impede readability of the validated JavaScript™ file.

15 . The method of claim 14 , wherein the generating of the validated JavaScript™ file comprises converting a Java™ data type into a JavaScript™ data type.

16 . The method of claim 15 , wherein the a Java™ data type is a Java™ date type and the JavaScript™ data type is one of “string”, “long”, and JSDate.

17 . The method of claim 11 , wherein the Java™ representation of the existing JavaScript™ file includes a Java™ function that can take typed-value-binding as an argument and return a value that is also a typed-value binding.

18 . The method of claim 11 , further comprising:

determining dependencies between JavaScript™ components in the existing JavaScript™ file; and

maintaining the determined dependencies to enable JavaScript™ aggregation and externalization.

19 . The method of claim 11 , further comprising facilitating authoring of the existing JavaScript™ file including building dependencies for the existing JavaScript™ file.

20 . A machine-readable medium having instruction data to cause a machine to:

access an existing JavaScript™ file;

validate JavaScript™ definitions in the existing JavaScript™ file;

generate a Java™ representation of the existing JavaScript™ file; and

generate a validated JavaScript™ corresponding to the existing JavaScript™.
