The point is to make JavaScript and its infamous browser-incompatibility problem completely transparent from application developers. By doing that, developers do not have to care about JavaScript any longer and it will become the machine language of the browsers. I do not care about the machine code since the appearance of Java and C#, neither do I want to care about JavaScript if you guys decide to generate it from Java/C#.
