Map.entries, Map.keys and Map.values should return iterator instead of array

[mweststrate]

See https://developer.mozilla.org/en-US/docs/Web/JavaScript/Reference/Global_Objects/Map/values

for backward compatibility, return both an array and iterator in the 2.0 branch?

You can return an iterator and have a third party library for the old behavior or map?

I think the library should make objects as indistinguishable from regular objects as possible.

released as 3.5.6 already.

@mweststrate why change them into iterator and not an array? as arrays you can easily user filter, slice, find , etc... what is the benefit of returning a MapIterator?

[benjamingr]

@Jony-Y spec compliance with regular ES6 maps.
