PhpStorm error: phpcs: Expected at least 1 space after "<"; 0 found

Good afternoon. I am encountering an incorrect error in PhpStorm. When using HTML inside JS files, I get the following PHPCS error:

return (
        <div>
            <h1>Таблица данных</h1>
            <table border="1">
                <thead>
                <tr>
                    <th></th>
                    <th></th>
                    <th>Дата отгрузки план</th>
                </tr>
                </thead>
                <tbody>
                {data.map((item) => (
                    <tr key={item.id}>
                        <td>{item.serial_number}</td>
                        <td>{new Date(item.deadline).toLocaleString()}</td>
                        <td>{item.productionItemPartStages?.length || 0}</td>
                    </tr>
                ))}
                </tbody>
            </table>
        </div>
    );

phpcs: Expected at least 1 space after

When I try to fix it, I get the following result:

return (
    < div >
        < h1 > Data Table < / h1 >
        < table border = "1" >
            < thead >
            < tr >
                < th > < / th >
                < th > < / th >
                < th > Planned Shipment Date < / th >
            < / tr >
            < / thead >
            < tbody >
            {data.map((item) => (
                < tr key = {item.id} >
                    < td > {item.serial_number} < / td >
                    < td > {new Date(item.deadline).toLocaleString()} < / td >
                    < td > {item.productionItemPartStages ? .length || 0} < / td >
                < / tr >
            ))}
            < / tbody >
        < / table >
    < / div >
);

That doesn't look like valid JavaScript to me. Maybe it's JSX? PHP_CodeSniffer does not support JSX.

Using PHP_CodeSniffer on JavaScript is discouraged, and won't be supported in the future. I recommend that you use a linter which supports the language that you are writing in. PHP_CodeSniffer works just fine for PHP.
