I agree with pretty much everything you said minus the Go one: if you are doing a CRUD app and you don't expect a huge traffic something like Python works well. Go shines for microservices though.

I can't talk about Node on the server since I don't use that - already doing way too much javascript for the frontends - but the frontend side is hard to keep up with as well.

Between all the Babel and Webpack plugins it's hard just to get a working setup and the `do one thing and do it well` should not be a bigger thing than user experience.

TypeScript makes writing JavaScript less painful but doesn't solve the ecosystem for me: I do rm -rf node_modules/ && npm install semi regularly to make sure everything works (not using shrinkwrap yet) on a fresh install and I get install errors way too often (peer dependencies etc).

To save you time, don't bother with npm3 for now as it is extremely slow.
