Purpose: Simplify usage
- [Instructor] Let's talk about the pattern that's all about simplification, the Facade. As a software developer, you might've encountered overly complicated APIs, classes with cumbersome interfaces, and methods you've never used. Using such components make our lives unnecessarily hard. The Facade pattern hides the complexity and lets us work with a more convenient interface. The Facade exposes a simpler set of public methods and properties. Clients communicate with the Facade, which in turn forwards the requests to the component it simplifies. The Facade not only simplifies the usage of complex interfaces, but it also decouples the consumer's site from these complicated frameworks. You may want to use the Facade when you only need a subset of the functionality provided by a type or framework. It proves to be useful also when working with components that tend to change frequently, like, for example, beta SDKs. Changes in these frameworks can be adopted in the Facade without…
