values() is not a function or its return value is not iterable

[piranna]

With the next code

[...mediasoupWorkers.values()]

being mediasoupWorkers an instance of multimap I get the error TypeError: mediasoupWorkers.values is not a function or its return value is not iterable. Seems like multimap doesn't fully implement the iterable and/or iterator protocol, just only return an object with a next method, and the coversion to an array doesn't works.

This equivalent code doesn't works too:

const result = []

for(const value of mediasoupWorkers.values()) result.push(value)

return result

Ok, according to https://medium.com/@insomniocode/javascript-iterator-and-iterable-protocols-583b700305ce, multimap implements the iterator protocol (the next() method), but it doesn't implements the iterable protocol (the one used by for..of and spread).

Iterating over the whole map is also not supported, but is in the native Map implementation

for (const [key, val] of map)

We would need to use an Array to keep record of the insertion order of the entries. We could iterate though it.
