some simple abstraction over target.addEventListener

eventListenerAbstraction.js

const eventListener = (target, type, handle) => ({
        on(alt, options) {

            this.options = options != undefined ? options : this.options || false;
            if (target.addEventListener) target.addEventListener(type, alt || handle, this.options);
            return this;
        },
