It is now only a matter of time, Mozilla has opened the way with JavaScript 1.7 . However, it is clear that the current JavaScript has limitations. For example, you can not protect you from a Reverse Engineering (see Reverse Engineering: the compressors of code ), we can make life difficult for those who want to scrutinize our code, but prevent it is highly unlikely.
The ECMA is based on which the current Javascript is unsatisfactory. Coming from Java, C + + 3.0 or ActioneScript, is noticeably uncomfortable in dealing with variables without specifying the type.
The structure is also primitive objects, with various differences in implementation (that will increase) in the different versions of the browser. Libraries like Prototype are designed precisely to overcome some limits of extension of the DOM, in addition to implement efficiently and cross browser Ajax (XMLHttpRequest).
Council to keep informed, to follow the evolution of Mozilla / Adobe / ActionScript on: ECMAScript 4
See the documentation of JavaScript 1.7: New in JavaScript 1.7
NOTE: FireFox 2.0.0.3 Released
