JavaScript React by Example Building the Application Adding Guests to the List

Shouldn't you prevent adding a guest without a name?

Since pendingGuest always holds at least an empty string, on submit keeps adding empty invitees when pushed. A simple if statement would prevent such action:

newGuestSubmitHandler(e) {
    e.preventDefault();
    if(this.state.pendingGuest.length > 0) {
      this.setState({
        guests: [
          {
            name: this.state.pendingGuest,
            isConfirmed: false,
            isEditing: false
          }, 
          ...this.state.guests],
          pendingGuest: ""
      });
    }
  };

That's a very practical program enhancement. The fact that you're thinking of effective improvements is evidence of your learning progress and grasp of the material. Good job! :+1:
