IE browser compatibility issue

I am using the list sorter which is causing the compatibility issue with ForEach function. _resetOtherWidgetsRendering: function() {             var others = document.querySelectorAll('.listSorter .sortIcon:not(.sort-none)');             var self = this;             others.forEach(function(el) {                 if (el === self.sortSpan) return;                 self._setSort(el, null);             });         }, To overcome this I am thinking to use Polyfill, but not sure how to use in every click event.
