SuperComponent

One of the goals of creating components is to be able to use them many times in your application. The instance returned after creating a component is called a SuperComponent, because internally each time the component is used a lightweight instance is created that manages this new rendering of the component, these instances take “control” whenever an action occurs in them where the reaction is the execution of a previously passed callback, normally in Hooks and DOM events.

Don't worry, it will become clearer as you go through the examples and practice.
