-If the browser doesn't support `Promise.allSettled`, it's easy to polyfill:
-
-```js
-if (!Promise.allSettled) {
- const rejectHandler = reason => ({ status: 'rejected', reason });
-
- const resolveHandler = value => ({ status: 'fulfilled', value });
-
- Promise.allSettled = function (promises) {

-In this code, `promises.map` takes input values, turns them into promises (just in case a non-promise was passed) with `p => Promise.resolve(p)`, and then adds `.then` handler to every one.
-
-That handler turns a successful result `value` into `{status:'fulfilled', value}`, and an error `reason` into `{status:'rejected', reason}`. That's exactly the format of `Promise.allSettled`.
-
-Now we can use `Promise.allSettled` to get the results of *all* given promises, even if some of them reject.
