Why is the code shown in three separate modules What would happen if the code for the two widgets were joined to the top module?

The code is organized into three separate modules to promote modularity, maintainability, and reusability. This separation allows each widget to be developed, tested, and updated independently, making the codebase easier to manage. If the code for the two widgets were joined to the top module, it could lead to increased complexity, making the overall code harder to read and maintain, and could also introduce potential conflicts and bugs when changes are made. Additionally, it would hinder the ability to reuse the widgets in different contexts or projects.
