Principles and practices for writing maintainable, modular code that can be used across multiple contexts
Core Idea:
Code reusability is the practice of designing software components that can be used in multiple contexts without modification, reducing development time, minimizing errors, and creating more maintainable systems.
Key Principles:
- Modularity:
- Breaking code into self-contained units with clear boundaries and single responsibilities.
- Parameterization:
- Designing functions and components to accept inputs that modify behavior without changing implementation.
- Interface Stability:
- Maintaining consistent methods of interaction with components even as internal implementations change.
Why It Matters:
- Development Efficiency:
- Dramatically reduces time spent solving the same problems repeatedly across projects.
- Bug Reduction:
- Centralizes fixes and improvements in one location that propagates to all usage instances.
- Consistency:
- Ensures uniform behavior and appearance across different parts of an application.
How to Implement:
- Function Extraction:
- Identify repeated code patterns and refactor them into standalone, named functions.
- Component Creation:
- Build UI elements with clear prop interfaces that allow for customization.
- Abstraction Definition:
- Create higher-order components or utility functions that encapsulate complex logic.

- Higher-Order Functions: Functions that take or return other functions for reusable logic
