What is the ‘prototype’ property of a React component?

MDN says that every JavaScript object has a prototype property that is not actually called prototype:

Every object in JavaScript has a built-in property, which is called
its prototype. … The property of an object that points to its
prototype is not called prototype. Its name is not standard, but in
practice all browsers use __proto__. The standard way to access an
object’s prototype is the Object.getPrototypeOf() method.

Why then do React components have a property called exactly prototype?

I can see this property from the Javascript console when creating a React app with create-react-app and logging App.prototype to the console:

const root = ReactDOM.createRoot(document.getElementById('root'));
root.render(
  <React.StrictMode>
    <App />
  </React.StrictMode>
);

console.log(App.prototype); 

The log returns an object.
