Best practices are the shortcuts that stop being shortcuts — the patterns experienced teams reach for because they have already paid for the alternative. This category collects them for the languages and frameworks you ship every day: how to structure a project, name things, handle errors, design an API, and write code the next person (often you) can change safely.
None of it is dogma. Every practice here comes with the reason behind it and the situations where it does not apply, because a rule you cannot justify is just cargo-culting. Where a pattern is easy to demonstrate, you can run the before-and-after in the editor and see the difference rather than take it on trust.
The through-line is maintainability: code that is readable, predictable and cheap to change. Easy to write and easy to delete beats clever every time, and most of these habits are about getting there without slowing down the work you are doing today.
