const items = [10, '10', 12, 15, 21, 12, 10, 16, 21, 15, 'apple', 'apple']; function createUniqueArray(values) { return values; }

To create an array with unique values from the original array, you can use the Set object, which stores only unique elements:

const items = [10, '10', 12, 15, 21, 12, 10, 16, 21, 15, 'apple', 'apple'];

function createUniqueArray(values) {
  return Array.from(new Set(values));
}

console.log(createUniqueArray(items));
// Output: [10, '10', 12, 15, 21, 16, 'apple']

Note that numbers and strings with the same content are considered different elements (10 and '10').
