before here probably refers to the variable in the script tag: (function(n,o,t,i,f) { n[i] = {}; var m = ['init', 'on']; n[i]._c = [];m.forEach(me => n[i][me] = function() {n[i]._c.push([me, arguments])}); var elt = o.createElement(f); elt.type = "text/javascript"; elt.async = true; elt.src = t; var before = o.getElementsByTagName(f)[0]; before.parentNode.insertBefore(elt, before); })(window, document, 'https://embed.novu.co/embed.umd.min.js', 'novu', 'script');
