How do I build this?

Start off by trying this without any hints. If you find yourself stuck, check out the HINTS.md file.

Stretch Goals

• Re-organize your code to make use of functions
• Allow the user to both complete and uncomplete to-do items
• Allow the user to fully delete a to-do item from the list
• Allow the user to edit the text of an existing to-do item
• Get creative! Add a new feature that you would find useful in a to-do list
