less dependencies, more freedom and independence!

But code reuse in OOP brings dependencies in. And I think dependencies which are clear defined, are not a problem.

I think we need to find an answer for that!

No answer for that ;-). Yes I agree, reducing unnecessary dependencies is a good point. But you always will have some dependencies which needs to be managed, even if it is a low number.

I really like your approach, in particular that you are not using reflection.

But you started from the same question like other Frameworks (ie. Robotlegs) did: “How can we handle this huge amount of dependencies in an easy, code less, way?”

Thats the wrong question.

The right one is: “How can we reduce dependencies?”
Do you have an answer for that?

I am absolute no Javascript guy, and my AS1 days are long gone… I think the basic idea should be portable but in a bit different style. You need to define somewhere a Class definition (prototype in js, right?) which will be used to create dynamically an object out of it. I guess that should be possible. You can pass the injector over the constructor and ask for the objects you want to get injected. That is basically a look up in an hash-map followed by a dynamic creation of an object from the class/prototype definition. The package level function/property style will probably not be possible in js.

Cool approach!

would it be possible to port it to Javascript?

Thanks
