Key Software Development Principles
When writing code, following established principles helps ensure maintainability, readability, and efficiency. Below are three fundamental principles every developer should know:
| Principle | Expansion | Meaning | Why It Matters |
|---|---|---|---|
| KISS | Keep It Simple, Stupid | Keep code and design as simple as possible. Avoid unnecessary complexity. | Simpler code is easier to read, maintain, and debug. |
| DRY | Don't Repeat Yourself | Avoid code duplication by reusing functions, modules, or abstractions. | Reduces redundancy, minimizes bugs, and makes updates easier. |
| YAGNI | You Ain’t Gonna Need It | Don’t add features or functionality unless they are required. | Prevents wasted effort, keeps the codebase lean, and improves maintainability. |
