Separation of concerns

Separation of concerns is a design principle in software development that involves dividing a program into distinct parts, each responsible for a specific function or aspect. This approach helps make the system easier to understand, maintain, and modify by isolating different responsibilities. For example, in a website, the user interface (what you see), business logic (how it works), and data storage (where information is kept) are separated. By doing so, changes in one area are less likely to affect others, leading to more organized and flexible software.
