Modularity
Modularity is a software design principle that involves breaking down a system into smaller, self-contained, and interchangeable components called modules. Each module encapsulates specific functionality and communicates with other modules through well-defined interfaces, promoting separation of concerns and reducing complexity. This approach enhances maintainability, reusability, and scalability in software development.
Developers should learn and apply modularity to manage complexity in large-scale projects, facilitate team collaboration by allowing independent work on modules, and enable easier testing and debugging. It is essential in scenarios like building microservices architectures, developing reusable libraries, or refactoring legacy codebases to improve code organization and reduce technical debt.
