These are the beginning of some smaller performance optimizations brought on by the v8 profiler. This includes removal or movement of over-reaching try/catch blocks and more disciplined argument handling, neither of which can be compiled into machine code (permanently, at least). This also removes some unneeded code, adds some baseline performance test cases, and begins generic performance test output and HTML generation which will be used in the future for more detailed analysis. This is just a starting point; there's more to come, guided by profiling. The trait implementation needs some love and, since its development is not yet complete, that will be optimized in the near future. Further, there are additional optimizations that can be made when ease.js recognizes that certain visibility layers are unneeded, allowing it to create more lightweight classes. Performance enhancements will also introduce the ability to generate a ``compiled'' class, which will generate a prototype that can be immediately run without the overhead of processing keywords, etc. This will also have the benefit of generating code that can be understood by static analysis tools and, consequently, optimizers. All in good time. |

GNU ease.js
GNU ease.js is a classical object-oriented framework for Javascript, intended to eliminate boilerplate code and "ease" the transition into JavaScript from other object-oriented languages.
Current support includes:
- Simple and intuitive class definitions
- Classical inheritance
- Abstract classes and methods
- Interfaces
- Traits as mixins
- Visibility (public, protected, and private members)
- Static and constant members
Documentation
Comprehensive documentation and examples are available on the GNU ease.js website and in its manual.
Bug Reports / Feature Requests
Please direct bug reports and feature requests to bug-easejs@gnu.org or the project page on Savannah.
Why Classical OOP in JavaScript?
GNU ease.js was created (historically) for a number of reasons:
- To "ease" object-oriented developers into JavaScript by providing a familiar environment.
- To provide the maintenance and development benefits of classical OOP.
- To provide features not included in the language, such as proper encapsulation through private/protected members, interfaces, traits, intuitive inheritance, and other conveniences.
- To encapsulate the hacks commonly used to perform the above tasks.
Many JS purists believe that classical object-oriented programming should be left out of JavaScript and that one should stick strictly to prototypal development. While the two are related (they are both object-oriented), they can be applied to different problem domains in order to achieve results that are more natural or intuitive to developers; GNU ease.js works seamlessly with existing prototypes, allowing the developer to choose whether or not they want to use "classes".
