programming-best-practices

Core programming principles for improving code quality include SOLID, DRY, KISS, and YAGNI. These language-agnostic guidelines help developers create cleaner, more maintainable code by establishing clear standards for program design and architectural structure.

To identify common code smells during a code review, evaluate the implementation against language-agnostic guidelines and metrics. Look for violations of SOLID principles and check quantitative metrics like cyclomatic complexity and cohesion to find areas for design improvement.

Cyclomatic complexity is a code quality metric that measures code maintainability by quantifying the number of linearly independent paths through a program's source code. High cyclomatic complexity indicates complex code that may require refactoring to reduce potential code smells.

Yes, you can use these design principles and metrics with any programming language. The guidelines are explicitly language-agnostic, providing universal best practices for code creation, review, and general program design regardless of the specific tech stack.

You should apply the YAGNI (You Aren't Gonna Need It) principle in software engineering when creating new features or reviewing code. It prevents over-engineering by ensuring developers only implement functionality that is actually necessary, directly elevating overall code quality.
