Build me a small JavaScript project for an Autumn 26 routine that helps me keep track of a simple daily or weekly schedule.

I want it to let me add, view, update, and remove routine items in a clean, easy way, and show the current routine clearly when I run it. Keep it straightforward and practical, with sensible defaults and helpful messages if something is missing or entered wrong.

If it makes sense, include a simple interface that is easy to use, and make sure the main routine logic is in one place so it is easy to change later. Please keep the code tidy and readable, and set it up so I can extend it without much effort.

Use whatever structure fits best for a small JavaScript app like this, and look up current docs online if you need to.
