Separation of concerns matters

Separation of concerns is an important principle in software development that aims to divide software design and implementation into distinct parts, each with a specific and well-defined responsibility. This principle helps developers create more maintainable and flexible applications by reducing the complexity of each individual component and allowing for more modular and reusable code.

In practical terms, separation of concerns means that different aspects of a system are separated and dealt with independently, without overlapping concerns.
