 * `join()` is a string operation instead of list operation. (sort of counter-intuitive at first usage)
-

   **💡 Explanation:**
   If `join()` is a method on a string then it can operate on any iterable (list, tuple, iterators). If it were a method on a list, it'd have to be implemented separately by every type. Also, it doesn't make much sense to put a string-specific method on a generic `list` object API.
