The concept of "separation of concerns" in web development is an important principle that aims to increase the maintainability and scalability of web applications. It refers to the idea of separating different functionalities or concerns into distinct and independent modules or components.
For example, separating the presentation layer from the logic layer allows front-end developers to focus on designing and implementing the user interface without worrying about the underlying business logic. Similarly, separating the data layer from the logic layer allows back-end developers to focus on implementing the business logic without worrying about the specific details of the database implementation.
Overall, the principle of separation of concerns helps to improve the maintainability, scalability, and flexibility of web applications, making it easier to develop and maintain complex systems over time.
