I disagree. My entire backend is written in Typescript and maintenance and feature development pace is incredible. It's been this way for years now and I cannot see myself switching to Go or Java anytime soon.
The pace is only "incredible" if you've never spent a year using a truly productive back-end language like Ruby, Elixir, or to a lesser degree PHP or Python.
Golang and Java are both tilted more towards performance and enterprise-friendliness than dev productivity and JS/TS are in the middle of the spectrum.
