Packages provide one of the best ways to structure multiple modules and small packages. It can help users to set the data hierarchy in a well-organized hierarchy manner and makes it quite easy for them to create and access any of the directories and modules as per their requirement.
It is just similar to folders and drivers available in our operating system, which help us to store multiple files, media, and much more. Similarly, if users learn to build packages, then it can help them to store other modules and sub-packages. Users can use and can modify any of the packages, as per their project needs whenever they want.
