Metadata

ID: jsx-react/jsx-no-comment-textnodes

Language: JavaScript

Severity: Warning

Category: Error Prone

Description

As JSX mixes HTML and JavaScript together, it’s easy to mistake text nodes and add comments to them. This rule prevents you from accidentally leaving comments as HTML text.

Non-Compliant Code Examples

    );
  }

      <div>
        /* empty div */
      </div>
    );
  }
