Who Is Your Favorite Child?

When we put some content inside the open and close tags of one of our components, we get access to it as the children prop.

const Parent = ({children}) => {
  return (
    <React.Fragment>
      <p>These are my favorites:</p>
      {children}
    </React.Fragment>
  );
}

const App = () => (
  <div>
    <Parent>
      Greg and Marsha
    </Parent>
  </div>
);

What happens if we also provide an explicit children prop to Parent?

const App = () => (
  <div>
    <Parent children={"Jan and Peter"}>
      Greg and Marsha
    </Parent>
  </div>
);

Which will take precedence when we destructure children in the parent component?

In the example above, we'll still see Greg and Marsha rendered. The content placed inside the tags will take precedence over the explicit children prop.
