My first computer book was: “Data Structures + Algorithms = Programs”. Thinking in this way has simplified my code tremendously. I think OO is taught because it’s more tactile. Literally it takes more keystrokes, and so much is pattern repetition that it facilitates learning and feels like progress. Functional is like learning Latin by studying Ovid one word at a time. When books (or mips) were expensive, this was how it was done. Even OO is old-school now though; today’s introduction to programming is mostly configuring CSS and webpack.
It often is, unless you solve a problem where it isn't (and at some point you will).
Nowadays I try to be very pragmatic about these things, but before I had a certain realization I just wanted things to fit neatly in classes and saw some beauty in it.
That was until I started using rust where this wish initially lead to a lot of frustration. When I finally gave in and did it the Rust "compositional" way, everything worked incredibly smoothly
