Error in definition of interface IteratorResult

[lord-saumagen]

Dear Ladies and Gentlemen,

I would like to bring to your attention, that the following interface is not conform to the specification in the "lib.es6.d.ts".

Currently defined as:

interface IteratorResult<T> {
done: boolean;
value: T;
}

The specification tells that the last IteratorResult returned form an iterator has the following values assigned:

done = true;
value = undefined,

So the correct interface definition would be:

interface IteratorResult<T> {
done: boolean;
value: T | undefined;
}

See the description ad MDN:

Kind regards,

Lord Saumagen.

Looks like a duplicate of #2983 and #11375
