What is more important than a programming language?

Question

Programming languages

I came across an entry like: “PL is just a tool, it’s much more important to study patterns, architecture ... and there was something else, but I can’t remember. So, what to study besides a programming language? What do patterns and architecture mean in programming? I need a detailed answer, I will be very grateful!

Answer 1
