This shortcut is inspired by @atnbueno’s series of JavaScript one-liners!

How to use

Run this using a Run Shortcut action with your array/list as input. The output will be your list removed of any duplicates.

Unfortunately, this will not work with image or media lists. However, I will be working on another Shortcut that might be able to do the task instead.

Note

Feel free to use this code wherever you want, no credit is needed!
