What Is the Empty Tag in React?

Learn about the empty tag in React

Introduced in React v16.2.0, the empty tag (<>...</>) in react is merely a shorter syntax for explicitly declaring fragments with <React.Fragment>. For example:

// ...

const Foo = () => (
    <>
        <li>Foo</li>
        <li>Bar</li>
    </>
);

// ...

Is equivalent to:

// ...

const Foo = () => (
    <React.Fragment>
        <li>Foo</li>
        <li>Bar</li>
    </React.Fragment>
);

// ...

Although the two syntaxes are equivalent, the key difference between the two is that the shorter syntax does not allow keys (or other attributes), while the full syntax does.
