Playground doesn't support async generators. #15
Description
I put the following code into https://www.typescriptlang.org/play/
async function f(): Promise<number> {
return 1;
}
async function* g(): AsyncIterator<number> {
yield 1;
await f();
return 2;
}The compiler reports two errors on the async function *g() line.
- Cannot find global type 'AsyncIterableIterator'
- Cannot find name 'AsyncIterator'
Is that expected?

The playground does not have a way to set compiler options, e.g. target, or
--lib. it is similar to microsoft/TypeScript#18209.The long term solution is to make it configurable. as a short term fix i will add the latest lib file.

Bump: it can't find
AsyncIterableIterator:reports

Also getting 'Cannot find name "AsyncGenerator"'

Setting the target to ESNext works with all these samples out of the box o the playground 👍🏻
