DRY (Don't Repeat Yourself)
The DRY (Don't Repeat Yourself) principle is a fundamental concept in software engineering that promotes code reuse. It states that if you have written a piece of code, then it should be reused throughout the codebase rather than repeated somewhere else. It advocates for avoiding duplication of code or logic and encourages developers to strive for a single source of truth. By adhering to DRY, you'll get the following benefits:
- Improved Code Quality: Duplicated code is prone to inconsistencies. By adhering to the DRY principle, developers ensure that code is written once and reused whenever needed, which greatly improves the quality of the system.
- Time and Effort Savings: Duplicated code requires redundant efforts. When changes or updates need to be made, developers have to modify the code in multiple places, which consumes time and also increases the risk of introducing errors. The DRY principle helps save valuable time and effort by centralizing code logic.
