💎 Compare

The function that removes all repeating elements, I code four methods, and made a comparison.

The array:

arr = [1, 1, 2, 5, 3, 1, 1, 2, 5, 3, 1, 1, 2, 5, 3, 1, 1, 2, 5, 3, 1, 1, 2, 5, 3, 1, 1, 2, 5, 3, 1, 1, 2, 5, 3]

The results:

By comparison, it can be seen that the performance of filter() is better, so the function adopts the filter().
