When I was younger I had a lot of trouble with OOP. It probably didn’t help that my two strongest languages at the time (PHP and Python) allow you to use them fully iteratively if you want. For some reason I never found an explanation that focused on state. A lot of the examples I saw I remember thinking it made a lot more sense to just rewrite the functions so they aren’t part of a class.

I still frequently see code examples online that are written using classes that don’t need to be. I imagine this is the reverse problem: people from languages like Java thinking everything has to be in a class.
