What aspect does modularity in programming enhance?

Modularity in programming significantly enhances the readability and maintainability of code. This approach involves breaking a program into smaller, manageable, and reusable components or modules. Each module encapsulates a specific functionality or piece of logic, which makes it easier for developers to read and understand the overall structure of the code. When code is modular, it allows programmers to focus on one aspect of the application at a time, fostering clearer organization and comprehension.

Additionally, when modifications are needed, changes can often be made within a specific module without affecting the entire application, which greatly simplifies the maintenance process. This modularity also allows for easier debugging and testing, as each module can be tested independently. Overall, the use of modularity leads to more maintainable and understandable code, facilitating collaborative efforts when multiple developers are involved in a project.
