I've been a Front-End Developer for a number of years and I'm very experienced with HTML, SCSS and intermediate with JS.
I'd like to learn how to build apps but also learn something server-side that could help me transition into either a Full-Stack Developer or Software Engineering role in the future.
I'm not sure whether to learn a framework (React, Node, Angular etc) OR go for the old classics (Python, C#, PHP).
I've seen that you can build a very successful app with Python, so at the moment I'm leaning in that direction - I'd just like to get the opinion of some other devs out there to see what you guys think.
Appreciate the help in advance,
