To fix code smells and improve maintainability, apply pragmatic coding standards like SRP, DRY, KISS, and YAGNI. Restructure functions to have a single responsibility, enforce naming conventions, and simplify control flow using guard clauses for predictable code.

The best way to structure functions and classes for readability is applying the Single Responsibility Principle to minimize complexity. Use clear naming conventions and componentization to reduce bugs and make the software structure easier to navigate.

Guard clauses simplify control flow by checking conditions upfront and returning early, which flattens nested structures. This approach reduces complexity, enhances testability, and keeps the main logic readable without deep indentation.

Yes, these coding standards apply across multiple programming languages and project sizes. The rules specify universal principles like DRY and KISS to enforce pragmatic coding guardrails regardless of the specific software environment or scale.

You should reconsider YAGNI when building core architectural foundations that explicitly require future scalability. However, to reduce code smells and complexity, you should generally avoid implementing features before they are needed.
