I just shipped Promise.allSettled in Chrome 76

index.js

const promises = [
	fetch('/api-call-1'),
	fetch('/api-call-2')
];

// Imagine some of these requests fail, and some succeed.

const results = await Promise.allSetted(promises);

// [
// 	{status: "fulfiled", value: Response}
//	{status: "rejected", value: typeError: Failed to fetch}
//]

// Now, all API calls have finished (either failed or succeeded).
