Woow, one million people... that's roughly like a population of Stockholm or San Jose 😄 

var oneMillion = 1000000;
var communityCount = getCommunityCount();

if (communityCount > oneMillion) {
    gs.print('High fives. Cake for everyone! 🥳');
}

 Congratulations!

PS: @laurenmcman Thanks for the new vocabulary lesson :)) It's the first time I hear "auspiciously" and obviously the AUS stands for 🇦🇺
