Adjacent elements in a React component without wrapping

To build a React component with multiple adjacent elements without wrapping them in a tag or container div, use React.Fragment:

render() {
    return <React.Fragment>
        <SubComponentOne />
        <SubComponentTwo />
    </React.Fragment>;
}

There is also a shorthand syntax:

render() {
    return <>
        <SubComponentOne />
        <SubComponentTwo />
    </>;
}
