Add/improve documentation for typing function components with access to children

With the introduction of React Hooks, the documentation recommends using function components instead of class components in the future.

However, I wonder how to define and type the component's properties when I want to access children components. I have come up with this solution (I am using Typescript):

import * as React from "react";
import "./styles.css";

type MyWrapperCompProps = {
  color: string;
  children?: React.ReactNode;
};

function MyWrapperComp(props: MyWrapperCompProps) {
  return <div style={{ backgroundColor: props.color }}>{props.children}</div>;
}

export default function App() {
  return (
    <div className="App">
      <MyWrapperComp color="tan">
        <h1>Hello World!</h1>
        <p>
          Lorem ipsum dolor sit amet consectetur adipisicing elit. Porro, fuga.
        </p>
      </MyWrapperComp>
    </div>
  );
}

This seems to work, but I have a couple of questions:

1. Is this the best practice to model wrapper components with children?
2. Is ReactNode the correct, most general type for children?
3. How does React automagically know that the children are assigned to props.children? Is this hardwired to the name children or is there anything I should be aware of?
4. Is the above documented anywhere at all on the React website?

Thanks a lot in advance for your help.

Comece pelo exemplo de componente wrapper em TypeScript desta issue e revise a documentação existente do site do React sobre componentes de função e children. Identifique o ponto de entrada apropriado da documentação e, em seguida, certifique-se de que as orientações relevantes respondam às quatro perguntas sobre tipagem, ReactNode, props.children e se o comportamento está documentado.
