Hi everyone!

Welcome to the FIRST edition of MongoDB $weeklyUpdate, a weekly digest of MongoDB tutorials, articles, and community spotlights!

We know, we know...MongoDB has been kinda AFK (away from keyboard) for a while on Dev.to, but that's all about to change! Each week, we'll be sharing the latest and greatest MongoDB content, curated by Adrienne Tacke at MongoDB:
