Missing / Incorrect Definition

IterableIterator, Iterable, Iterator

Sample Code

While working on some VS Code api, we realized we don't understand what an IterableIterator is compared to Iterable. It would be helpful to document these interfaces because they are used in the stdlib and for any code authors who may be using them too

const m = new Map();
m.entries() // look at type here
