It's always difficult to start a new project or the implementation of a new feature. We just don't know how to structure our code, what modules to write, and how they are going to communicate. In such cases, we often trust well-known practices—design patterns. Design patterns are reusable solutions to commonly occurring problems. For example, the Model-View-Controller pattern has proven to be one of the most effective patterns for web development due to its clear separation of the data, logic, and presentation layers.
