It would be nice if there was a Rails of javascript, but there seems to be a lot of competing technologies. Obviously, you can learn new things at a new job, but it would still be better to learn something with a lot of adoption. I'm thinking a MEEN stack (using ember instead of angular) or even using react and flux. Meteor is another choice, but I'm not sure how widely adopted it is. I think it would be best for him to pick one stack and master it well before moving on.
It's annoying because, when it comes to Rails, I know exactly what skills a beginner needs to learn. Does anyone know what the more successful js bootcamps like hack reactor teach? Or do you have any advice on a good stack for a prospective full stack js developer to learn?
