The concept of “Separation of Concerns” (SoC) is a fundamental principle in programming and software engineering. It dictates that a program should be split into distinct sections, each addressing a separate part of the functionality. The principle is akin to an assembly line in a factory, where each worker is responsible for a specific task. In the realm of programming, this translates to dividing code into segments that handle specific aspects of the application, leading to a more organized, manageable, and efficient development process.

Why Separation of Concerns is Important in Programming

Enhanced Readability and Maintenance: By segmenting code, developers can focus on one aspect of the application at a time. This division makes the code more readable and easier to understand. When each part of the code is responsible for a single functionality, it simplifies the process of finding and fixing bugs, updating features, or making any modifications.

Increased Reusability: SoC promotes the creation of reusable code. When code is divided into distinct sections with defined responsibilities, these sections can…
