Party invitations

Build an app to make invitations for a party. It starts like this:

Note: The Invite button is disabled.

The user types in a name, and clicks either the snack or dessert button. If there's no name, show an error message.

• The snack and dessert counts at the top of the page are updated.
• The snack and dessert buttons are disabled.
• The invite button is enabled.

When the user clicks the Invite button:

• An invitation is created, and added to the existing invitations.
• The invitation heading, and the invitations, are shown.
• The snack and dessert buttons are enabled.
• The invite button is disabled.
• The name field is cleared.

Here's what the screen might look like after some invitations:

Sign the invitation with your name, not mine.

Hints:

• To disable a button: $("#dessert-button").attr('disabled','disabled');
• To enable a button: $("#invite-button").removeAttr('disabled');
