Completely agree with the post. Angular.js is like a spring framework for javascript, except javascript is simple and elegant by itself and does not really need spring framework. I also agree that React provides real value and here to stay.
backbone.js+jQuery+ROR+Mongo
I find this selection easy to use an powerful.
backbone.js+jQuery has a lot of adoption and strong community, so it's easy to find answers and additional components.
ROR got strong community and language. Almost every functionality is available as a gem with code published on github.
