This function is available from LeekScript 4 onward. Returns a new set containing the keys of the map map, in the order of the map.

Same as arrayToSet(mapKeys(map)), without the intermediate array. The set is a copy: modifying it does not modify the map.

Parameters

• map: The map.

Return

• keys: The set of the keys of map.

Note

• Costs 1 operation, plus 2 per key.
