Model–view–controller (usually known as MVC) is a software design pattern commonly used for developing user interfaces that divides the related program logic into three interconnected elements. This is done to separate internal representations of information from the ways information is presented to and accepted from the user.

The job of a controller is to listen for a request from the front-end, take the appropriate action, and return (or redirect) with its response. It serves as a reactionary mechanism for front-end calls. Controllers are full of actions, which are the methods that specifically handle requests.

Application services implement business use cases and are decoupled from the presentation layer, whether it be MVC or something else. In turn, application services can host transaction scripts or a domain-driven design. To re-iterate from the previous post on this subject, what you're exactly separating from controllers and services is the business logic from the web/HTTP logic. So your controllers handle some basic things like validation, pulling out what data is needed form the HTTP request (if you're using Express, that's the req object) and deciding what service that data should go to.
