Suggestion

https://github.com/tc39/proposal-promise-allSettled is Stage 3 now

Checklist

My suggestion meets these guidelines:

• This wouldn't be a breaking change in existing TypeScript/JavaScript code
• This wouldn't change the runtime behavior of existing JavaScript code
• This could be implemented without emitting different JS based on the types of the expressions
• This isn't a runtime feature (e.g. library functionality, non-ECMAScript syntax with JavaScript output, etc.)
• This feature would agree with the rest of TypeScript's Design Goals.

Giving this a bump since I intend to add this to the node type definitions.

Also, the description for this issue says Stage 3, but it was moved to Stage 4 roughly 2 months ago (https://github.com/tc39/proposals/blob/master/finished-proposals.md). It should probably be added to es2020, and not esnext.

This is already supported in Node 12.9.0, I think it should be added to TS natively. There's a @types definition for this but I didn't manage to get it to work though...

Why am I not able to use these types in the playground?

The playground has a constant single dts file for all the lib files. This doesn't get updated per version, and I've not got around to an expensive to download but more accurate version yet - you can follow microsoft/TypeScript-Website#82 for updates there
