It's full of stupid comments. E.g. the python implementation has this attached.

```py """Warning: This code completes in a shocking O(n log n) time complexity and allocates memory with reckless abandon""" ```

How shocking that sorting is an O(n log n) algorithm.

Edit: he then goes on to use bubble sort.

I think there might be a large amount of tounge in cheek with this blog post, but it doesn't really land.
