Create a Unique Sorted Set from an Array

You're working on a data analysis project where you need to ensure that your data is clean and free from duplicates. You have been given an array of numbers, and your task is to transform this array into a set—a collection of unique items—by removing all duplicate values and sorting the remaining elements in ascending order.

Instructions:

• Write a function named createUniqueSet that takes one parameter:
  • arr: An array of numbers that may contain duplicates.
• The function should return a new array that contains only the unique numbers from the original array, sorted in ascending order.

Note: Only use the map, filter, or reduce methods, or a combination of these methods, to solve the problem. Do not use loops to iterate or perform the operation.

Example 1

Input: createUniqueSet([5, 7, 8, 9, 10, 15]);
Output: [5, 7, 8, 9, 10, 15]

Example 2

Input: createUniqueSet([4, 4, 4, 4]);
Output: [4]

Example 3

Input: createUniqueSet([3, 3, 3, 2, 1]);
Output: [1, 2, 3]
