What is a class component in React?

Question

React

More precisely, I understand that such an entry is called class component (class component), but why not component class (component class)? After all, the second option would be more correct, or tell me how to translate into Russian - the component class? Otherwise, how to understand then the class component, what does it mean?

class App extends React.Component {
  constructor(props) {
 super(props)
 this.state = { username: 'johndoe' }
  }
  render() {
 const { username } = this.state
 return(
 <div>
 { username }
 </div>
 )
  }
}

In this case, class is the type of the component. It is more correct to translate not "class component", but "class component", as opposed to functional
