Another option is to attach the on method plus Array.prototype.map to the NodeList prototype instead:
const$$=(selector,startNode=D)=>startNode.querySelectorAll(selector)NodeList.prototype.map=Array.prototype.mapNodeList.prototype.on=function(type,listener,options){this.map(el=>{if(elinstanceofElement){el.addEventListener(type,listener,options)}})returnthis// for chaining}
This keeps the Array prototype clean =).
