Additional project with TeamTreehouse
- validation
- reject empty strings from being added
- append a message to the DOM when you pass empty strings
- checkbox
- confirm -> confirmed when the box is checked (text nodes)
- create addition text area for a note function or checkboxes using select element instead of checkbox
- to improve a user experience, make the hide button to remove invitees who already confirmed
