MailerLite provides a js snippet to embed a form. The snippet works fine in an html file, but for some reason errors out in a jsx file

   (function(w,d,e,u,f,l,n){w[f] = w[f] || function () {
        (w[f].q = w[f].q || [])
        .push(arguments);
      }, l = d.createElement(e), l.async = 1, l.src = u,
        n = d.getElementsByTagName(e)[0], n.parentNode.insertBefore(l, n);})

Returns an error of '}' expected ?

Very confused
