I am 40 this year and next year will be 20 since my first paid job. I am more than confident that I'll be all right in 10 years time. I did desktop apps with Delphi, all kinds of websites with php/mysql/jquery, worked on a media streaming system for video calls, developed ci pipelines, tools to compile code on a server and run it on thin clients, recently reactjs apps, django backend, code generators, you name it. It's al the same blipping thing. It's just code that gets executed when other code says so. You should poke every known piece of tech you can, be it react, vue, jquery, or django, ror, .net. You should mess with aws, gpg, azure, cloudformation and terraform. Mess with arduino or another microcontroller. At some point you will start seeing patterns and understand that conceptually, a reactjs front end is not that much different than a backend service written in c++. This is a career long thing, but it gets easier the more you do it. The moment you decide you learned enough, you should start preparing to be discarded. As an aside, the more you search for patterns, the easier it gets to internalize new tech and understand the benefits. And painfully obvious that some of the new tech is... just new, sometimes even worse.
