Write the const variable names inside the header tag instead of copying and pasting the h1 and p elements?

While rewriting our code to use JSX, Gil manually copies and pastes the h1 and p elements inside the header JSX element like so 

 const header = (
    <header>
        <h1> My First React element</h1>;
        <p> I just learned how to create a react node and render it into the dom</p>;
    </header>
);

This seems somewhat counter intuitive. Is there a way were we can simply write the variable names inside the header tag, like so?

 const header = (
    <header>
        title
        desc
    </header>
);

For other users:

const title = "my title";
const desc = "my desc";

const header = (
  <header>
    <h1>{title}</h1>
    <p>{desc}</p>
  </header>  
);

ReactDOM.render(
  header,
  document.getElementById('root')
);
