Here's the original post I responded to: > > The interfaces between server- and client-side code should be well-defined and language-independent. > They dont have to be and that is the point. If you write JS/TS front and back you can make everything much simpler with the associated benefits. That post implies that if you're writing in the same language on the front and back ends, it not only makes writing that language easier, but also somehow makes it easier to marry the two. Since most web services operate through some sort of HTTP interface, which is language agnostic, I can only infer that that poster somehow meant code reuse. So there's that, plus I've seen countless times before over the years where people explicitly tout code reuse as the primary benefit to using JS on the backend. I'm not buying any of it.
