Your first component

A React component is a JavaScript function that returns markup. Component names start with a capital letter: lowercase tags are treated as plain HTML elements. Components can use other components, and you can put each one in its own file and export it.

function Profile() {
  return <img src="https://i.imgur.com/MK3eW3As.jpg" alt="Katherine Johnson" />;
}

export default function Gallery() {
  return (
    <section>
      <h1>Amazing scientists</h1>
      <Profile />
    </section>
  );
}
