- Open-Closed: Welcome change with open arms, allowing new features to seamlessly integrate without breaking existing functionality.
- Liskov Substitution: Replace objects seamlessly, ensuring that derived classes can gracefully stand in for their parents.
- Interface Segregation: Avoid bulky interfaces that burden classes with unnecessary functionality.
- Dependency Inversion: Turn the tables on dependencies, making higher-level modules independent of lower-level details.
Coding Conventions: The Code Style Police
Imagine a world where code roamed free in a chaotic, inconsistent jungle. Coding conventions swoop in like fashion police, bringing order and uniformity to this unruly realm. They enforce consistent naming, indentation, and formatting, ensuring that every line of code flows in perfect rhythm.
Self-Documenting Code: The Gift of Clarity
Clear code is like a well-written book—it speaks for itself. Instead of drowning your code in a sea of comments, strive for self-documenting code that explains its purpose through descriptive names and well-structured design. This approach frees you from the burden of excessive annotation.
Testing, Testing: The Bug-Squashing Cavalry
Bugs, like pesky mosquitoes, are an inevitable part of software development. But regular and thorough testing can swat them away before they wreak havoc. Unit tests, integration tests, and acceptance tests form a mighty army against software defects.
Refactoring: The Art of Code Rejuvenation
Just as we must tend to our gardens to keep them thriving, so too must we refactor our code to maintain its health and vitality. Refactoring is the art of reworking existing code to improve its structure, readability, and maintainability without altering its functionality. It’s like giving your code a rejuvenating spa day.
