Besides some of the very, very obvious (don’t copy/paste 100 lines of code, make it a function! Write comments for your future self who has forgotten this codebase 3 years from now!), I’m not sure how to write clean, efficient code that follows good practices.
In other words, I’m always privating my repos because I’m not sure if I’m doing some horrible beginner inefficiency/bad practice where I should be embarrassed for having written it, let alone for letting other people see it. Aside from https://refactoring.guru, where should I be learning and what should I be learning?
Alright. I thought from my post it was clear I meant “How do I write code that follows good standards? How do I learn the rules of thumb about how to write good code?” by “code that follows good practices”. I suppose you can sum that up as “the practice of writing good code”, closer to the sense of “the practice of law”, although I wasn’t originally thinking of it that way, hence my confusion. Did I make some grammatical error that made it hard to interpret? I’d like to know so I can avoid such problems in the future. If it’s worth anything, English is my native language and I am aware of those two senses of “practice” you mentioned.
