231,269 PointsI don't think I've ever seen anyone ask that question before, and while it might have some value, the main focus of coding should be functionality. There are a few functional issues here that can be addressed.
It's not a good idea to mix interactions like prompt or alert with document writes. The document will generally not be visible until the function creating it is done and exits.
I see someone "fixed" your code presentation. But unless they also changed the functionality in the process, the purpose of the code is unclear. You print your list (which is not yet visible), ask for a choice, print the choice index value, then the list again (modified), and then the original and modified lists combined - and all one one line.
Here's the document that was created when I entered "list", "milk", and "quit" (nothing but the prompts were seen until after "quit"):

Is that what you intended it to do? I suspect not.
So, focus on making your code work as the primary objective. Worry about "succinct" after it runs perfectly.
