Description: The Express Router is a fundamental tool within the Express.js framework, designed to facilitate the creation of modular and mountable route handlers in web applications. It allows developers to organize their code more efficiently by separating routes into different modules, which enhances code readability and maintainability. Each router can handle a specific set of routes and associated logic, allowing for a clearer and more scalable structure in large applications. Additionally, routers can be nested, meaning that hierarchies of routes can be created, further facilitating code organization. This modularity is especially useful in complex web applications, where different parts of the application may require different sets of routes and controllers. In summary, the Express Router not only optimizes route management but also promotes good development practices by allowing a clear separation of responsibilities in the code.
