Global Coding Style

Consistent naming and formatting reduces cognitive load and technical debt by making code intent explicit. Apply intentional naming for variables and functions, break logic into single-responsibility units, and enforce automated formatting with tools like Prettier, ESLint, Black, or Ruff across your codebase to ensure maintainability.

Break functions by responsibility: each should do one thing clearly. Extract logic into named functions with descriptive names, use guard clauses to surface invalid states early, and document trade-offs. Verify changes with tests to ensure behavior is preserved while improving readability.

Configure formatters and linters appropriate to your stack—Prettier and ESLint for JavaScript, Black and Ruff for Python, and equivalent tools for other languages. Apply them consistently across all code to enforce style rules automatically, reducing manual review friction and ensuring uniform conventions.

Yes. Global coding style principles like intentional naming, single-responsibility functions, guard clauses, and explicit side effects apply across languages. Configure language-specific formatters and linters to implement these rules uniformly, making your codebase consistent regardless of the tech stack.

Dead code increases maintenance burden and obscures intent. Removing unused code, variables, and functions clarifies what actually runs, reduces cognitive overhead during reviews, and prevents confusion about deprecated logic. Automated tools and tests verify dead code removal is safe.
