2,522 PointsAny reason not to just pass the function into the Counter props and not have to declare a variable on each render?
Like this:
<Counter
totalGuests={this.getTotalInvited()}
guestsAttending={this.getTotalConfirmed()}
guestsUnconfirmed={this.getTotalUnconfirmed()}
/>

const numberUnconfirmed = totalInvited - numberAttending;
He doesn't want to create a third function. It's personal preference. I like you way.
