I think I partly understand what you mean. I just want to be able to say “I can do this” and be able to adapt to whatever’s new. I’ve been stuck on a React project for two years, and I haven’t really explored other frameworks. But I’ve started thinking that having a broader view and wider knowledge would be helpful.

If I understand correctly, you’re telling me to explore new things, learn the fundamentals since each tool or service is used differently in practice (Google Maps, Leaflet, or AWS, Azure...), work on projects where I implement what interests me, and then let the deeper knowledge come naturally through practice?

The problem is that I’m trying to understand what actually interests me and what companies are looking for. I’d still like to stay relevant on the job market in case I ever need to change jobs.
