“Generally speaking, a context encapsulates all business logic for a common purpose. This way, we can interact with our business logic from controllers, channels or remote APIs, without having to duplicate code. In a nutshell, a controller exists to work with context functions. It parses end user requests, calls context functions and translates those results into something the end user can understand. Each slice of code has an isolated purpose. The context doesn’t know about the controller, and the controller doesn’t know about the business rules.”
