The returned array contains the corresponding property of the source object for each key in keys, in order. For example:permute(["a", "b", "c"], [1, 2, 0]); // returns ["b", "c", "a"]It is acceptable to have more keys than source elements, and for keys to be duplicated...
If you change a reference to an object in one array, only that array has a reference to the new object. However, if two arrays contain references to the same object, you can observe changes to that object’s properties from both arrays. For example: // An integer type with reference ...
