Modularity

Modularity is like playing with Legos. You can take various Lego blocks and put them together to make different structures or objects. Each block has its own shape and size, and you can mix and match them to create something new.

Similarly, in the world of programming, modularity means breaking down a big problem into smaller problems and creating small, independent parts that can be combined and reused to solve different problems. Just like different Lego blocks can be combined to create a castle, a car or a boat, different software modules can be combined to create a website, an app or a game.

Modular programming makes it easier to manage complex codebases by dividing the work among different teams, minimizing the impact of changes to one part of the code, and allowing for faster development and testing. It's like having a big box of Legos, each with its own function, that you can use to build anything you want.

In summary, modularity is a programming practice that helps developers break down a big project into smaller parts, which can be combined and reused in various ways to make software development faster, more efficient, and easier to manage.
