Checks if two IMapMapped instances are structurally equal.
Two IMapMapped instances are considered equal if they have the same size and contain exactly the same key-value pairs. The comparison is performed on the underlying mapped keys and values, so the transformation functions themselves don't need to be identical. Values are compared using JavaScript's
===operator.Performance: O(n) where n is the size of the smaller map.
