@loke @scitesy that is true. Though, I think I would need to see a clear cut advantage of diverging the technology before taking on the complexity of learning/integrating two ecosystems. There are also advantages to having the technology the same on both sides that would otherwise not be realized...such as sharing data models and validation logic.
@scitesy Sure, I'm not saying that there are no advantages to having the same language on both sides. What I am saying is that as a benefit it's less important than having good tools.
The belief that having the same language on both sides is the most important factor is what gave us Nodejs.
