const errorHelpMaybe = (func) => {
try {

const { name, message } = err;

Computer feature test of the highest order.
(function fanTest () {
'use strict';
var i = 1;
while (i) {
i = i + 1;
// Let's be nice and not throw errors in browsers that don't have consoles ...
if (!!console) {
i < 10000 && console.log('These fans work great!');
