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?
Often the order that if/then are placed in can make ‘else’ unnecessary. "Exit early"is the guiding principle.
The reason to avoid ‘else’ is because if an if/then can be resolved in a few lines of code, it reduces nesting, which can make the code dramatically more readable and maintainable.
