Interface Segregation Principle Explained: Stop Writing "Fat" Interfaces
Are your interfaces trying to do too much? The "Fat Interface" is a common design smell that leads to bloated, fragile code and frustrated developers. In this video, we break down the **Interface Segregation Principle (ISP)**—the 'I' in SOLID—and show you exactly how to fix it.
We explore why forcing clients to depend on methods they don't use is a bad idea and demonstrate how to refactor a massive "God Interface" into clean, role-specific components.
