> Not 1 year you can write the same kind of code (professionally), every month new libraries you have to use

Huh, that's weird, because I've been writing in Angular & React and using the same basic libraries for years now. And before that it was jQuery and Handlebars and a lot of the same basic libraries for years.

I've made two large shifts in JS development over a decade.

Not sure why you seem to need to switch every month?
