Just as the title, what does mean in React? Like this code below.

 <>
   <h1> Just a simple header </h1>
 </>
);

These are shortened syntax for code fragments https://reactjs.org/docs/fragments.html

...There is a new, shorter syntax you can use for declaring fragments. It looks like empty tags...

This is the short syntax of React.Fragment. However, be in mind that that it doesn’t support keys or attributes. If you wanna add key or attributes. You should use back the original syntax

<React.Fragment myOwnProps={...sth} key={...otherThing}>
      <div>...</div>
</React.Fragment>

React fragment https://reactjs.org/docs/fragments.html

it's just a shortened syntax

This:

return (
    <React.Fragment>
      <ChildA />
      <ChildB />
      <ChildC />
    </React.Fragment>
  );

Equal to this:

return (
    <>
      <ChildA />
      <ChildB />
      <ChildC />
    </>
  );
