@ -177,14 +177,13 @@ If the browser doesn't support `Promise.allSettled`, it's easy to polyfill:
```js ```js
if (!Promise.allSettled) { if (!Promise.allSettled) {
const rejectHandler = reason => ({ status: 'rejected', reason });
const resolveHandler = value => ({ status: 'fulfilled', value });
Promise.allSettled = function (promises) { Promise.allSettled = function (promises) {
return Promise.all(promises.map(p => Promise.resolve(p).then(value => ({ const convertedPromises = promises.map(p => Promise.resolve(p).then(resolveHandler, rejectHandler));
status: 'fulfilled', return Promise.all(convertedPromises);
value
}), reason => ({
status: 'rejected',
reason
}))));
}; };
} }
``` ```
