Code Reuse

Code reuse is a software development principle that involves leveraging existing code components, such as functions, classes, or modules, across multiple parts of a project or different projects to avoid duplication. It promotes efficiency, consistency, and maintainability by reducing redundant work and minimizing errors. This concept is fundamental in programming and is implemented through techniques like libraries, frameworks, and design patterns.

Also known as: DRY Principle, Software Reusability, Code Recycling, Component Reuse, Reusable Code

🧊Why learn Code Reuse?

Developers should learn and apply code reuse to save time, improve code quality, and enhance scalability in software projects. It is essential in large-scale applications, team collaborations, and agile development where reusing tested and optimized code reduces bugs and speeds up development cycles. Use cases include building modular systems, maintaining legacy code, and adhering to DRY (Don't Repeat Yourself) principles to avoid redundancy.
