I have followed the same path as you when i started "re-inventing" myself as a JS engineer. Started on React, ES6, ES7 and a lot of different packages and then slowly started moving on towards back-end, NodeJS, Express, etc.
Noticed same exact issues, backend and way more stable and even fun place to be also IMO even more easier to work with.
On FE simply there is just too much to worry about and too much to learn and FE is less standartized then backend.
Not saying that we shouldnt update our knowledge, we should update our knowledge but its another thing learning new stuff and putting them to practice and another thing being afraid to update a simple dependency because it could break your whole app.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
