You misunderstand why people think JS is insecure. The problem is that JS is really easy to make mistakes in because of silent errors, dynamic typing, type coercion, etc.<p>The result is that your server-side JS is more prone to different kinds of security issues.<p>On the client side, in the browser, JS is sandboxed, so the language is almost irrelevant. If JS can&#x27;t actually access the underlying system, no number of bugs make the code insecure.
