I'm talking about a great front end developer experience. Rails was crap. Spring * was crap. None of the back end frameworks came close to thinking in abstractions - code reusability was an afterthought at best. Ask yourself, why was there never a Rails component library? Because Rails made abstraction difficult in the front end. Nobody did a good job here.
