[wongteam]

Hi! Thanks for nice example! But i was found an error when try to test this example in my browser.

1. Open localhost:3000
2. Add a friend
3. DELETE ALL FRIENDS
4. Add new friend
5. Add another friend and will a little fail. New friend name just replace exists that added before! I don't know why it doing, and hope if you have time then you will fix it.
