What's not emphasized in the article is that these days nobody wants generalists anymore. Companies don't even want front-end/back-end devs. They are specifically looking for React/Angular/Vue; or "GraphQL proficiency"; or Spring/Django/Node/etc. On the one hand, recruiters spam you with emails without a single mentioning of any language stack.
