Building Enterprise JavaScript Applications

I didn't find it too out of date. I used the latest versions of everything and the only thing I had to update myself was the React section for the frontend to use hooks. Packt books regularly go on sale for $5-$10 so you can also wait for one of those.

VERY interested in "Building Enterprise JavaScript Applications" I noticed that it was released Sept 2018. That's not too old, but I'm curious if there's a more up-to-date version.
