Implement the function unique_in_order which takes as argument a sequence and returns a list of items without any elements with the same value next to each other and preserving the original order of elements.

The argument can contain a string or an array.

For example:

uniqueInOrder([1,2,2,3,3]) should return [1,2,3]

uniqueInOrder('ABBCcAD') should return ['A', 'B', 'C', 'c', 'A', 'D']

• uniqueInOrder('AAAABBBCCDAABBB') should return ['A', 'B', 'C', 'D', 'A', 'B'].
• uniqueInOrder('ABBCcAD') should return ['A', 'B', 'C', 'c', 'A', 'D'].
• uniqueInOrder([1,2,2,3,3]) should return [1,2,3].

let uniqueInOrder = (iterable) => {
  //your code here - remember iterable can be a string or an array
};
