yup this comment trail is pretty dead-on.

The problem with web dev (I've thought about this a lot) is really that the browser is kindof the hinge. So no matter what you do for unifying languages, even porting modules so they're same on node front to back-end... you still can't really ever get to a point where you're unit testing pretty reliably through the full-stack.

So might as well test parts in isolation & who cares if there is one language throughout the whole stack as long as your devs are good at the languages required.

One day I think the impedance between server & client will disappear, but only when the browser's role as a rendering engine diminishes or finds better integration/intimacy with the codebase.

(and incidentally, i stopped caring so much about this struggle once i learned how to develop pretty reliable SOA. Haven't totally given up trying to conceptualize the perfect stack tho)
