Issue #88

Hi Readers!

Well I had a great time at Chain React again this year! Met so many nice people, ate some great food, and even got in a workout session.  As you might have heard, Facebook announced Hermes, a new JavaScript engine optimized for React Native. You can see the video of the actual unveiling in the "Frank's Picks" section below. Until much of the info from Chain React is processed and blogged about, we've got a hodgepodge of goodies for this issue.

So Enjoy!
