Not actually a question just a good extra feature i added

So I hit enter and it added a blank invite which seems buggy to me. To fix this I added an if statement reading... if(input.value == ''){ return false; } Wanted to share just because if it bothered me I'm sure someone else was thinking about it too.

The course examples are kept intentionally simple, but that's a nice example of the kind of improvement that can make a real-life UI more "friendly". :+1:

Now if you wanted to get really fancy, you could disable and dim the button while the input has no valid content. :wink:

this only is valid if we click submit button without entering anything. but if we just key spacebar 3 times and then submit then it take the entry. How can we fix that?
