Keep Functions Small and Names Meaningful

Writing code that’s easy to maintain starts with small, focused functions and descriptive names. A function should do one thing and do it well; if you find yourself adding unrelated logic, split it. Use nouns for variables and verbs for functions, and keep the naming consistent—this makes the intent obvious to anyone reading the code later.

Regularly add concise comments and automated tests for non‑obvious sections. Comments should explain the why, not the what, and tests give you confidence when refactoring. By pairing clear naming with documentation and tests, the codebase stays understandable as it grows.
