# Clean Code Principles Use these when you write, review, or refactor code. Treat these as directional principles. Where a repo's established precedent or a language's own idioms conflict with a rule here, follow the local convention and match the surrounding code. --- ## 1. Naming & Readability ### 1.1 Avoid Disinformation Never use variable names that create false expectations, contain misleading technical terms, or use visually confusing characters. **Do:** - Use names that honestly reflect the data structure (`accountsMap`, `accountsGroup`). - Use distinct names for classes/variables so autocomplete doesn't trick you. **Don't:** - Name a map `accountList` just because it holds several items; to a programmer "list" means an indexed structure. - Create names that vary in tiny ways (e.g., `ABCManagerForEfficientProcessingOfUsers` vs `...PersistingOfUsers`). - Use characters that look identical (lowercase `l` vs `1`, uppercase `O` vs `0`). - Bad: `int a = l; if (O == l) a = O1; else l = O1;` ### 1.2 Make Meaningful Distinctions If two things have different names, they must do different things. Avoid meaningless noise words and number series. **Do:** - Reveal the actual role of variables (e.g., `array`, `condition`, `transformation`). - Use specific, role-based names for classes (e.g., `OrderValidator`, `OrderRepository`, `OrderCalculator`). **Don't:** - Add meaningless noise suffixes when you can't think of a better name (e.g., `OrderManager`, `OrderHandler`, `O...
