I usually code a backend in Go or Python, but recently been thinking if I should just abandon my "prejudice" (JS sucks, Node sucks, Node is single threaded, there are no SQL libraries, etc) and move to JS on the backend as well, since that's what I already use on the frontend - be it web or React Native.

(I actually find JS very expressive and oriented towards a style of "table-oriented programming" which is useful for software that changes a lot like UI, IMO).
