Modules
Modules are a fundamental programming concept that involves organizing code into reusable, self-contained units to manage complexity and promote maintainability. They encapsulate related functions, classes, or variables, allowing developers to import and export functionality across different parts of an application. This concept is implemented in various forms across programming languages and frameworks to support modular design and code reuse.
Developers should learn and use modules to structure large codebases effectively, avoid naming conflicts, and improve collaboration in team environments. They are essential for building scalable applications, enabling features like dependency management, lazy loading, and testing isolation, particularly in modern web development, backend systems, and software libraries.
