getAndRemoveDuplicates(array): any[]
Removes and returns every extra instance of unique items in array.
NOTICE: The function will error if array contains an object.
'object' does not include arrays. Arrays are OK.
Examples
let arr = [1, 2, 3, 4, 1, 2, 3, 4, 5, 2];
let duplicates = getAndRemoveDuplicates(arr);
// arr is now [1,2,3,4,5].
// duplicates is now [1,2,2,3,4]
// (In returned duplicates, identical items are always side-by-side)
let arr = [1, 2, ['a','b'], 9, 1, 2, 3, 4, ['a','b'], 1, 9, ['a','b']];
let duplicates = getAndRemoveDuplicates(arr);
// arr is now [1, 2, ['a','b'], 9, 3, 4]
// duplicates is now [1, 1, 2, ['a','b'], ['a','b'], 9]
// This will trigger error, because arr contains object:
let arr = [1, 2, {prop:1}, 2, 3, 4];
getAndRemoveDuplicates(arr); // Error!
