This is an excellent tutorial. I have been looking for something like this forever: "One should be able to learn React Native directly through this tutorial, without starting with React" Thank you!

#52Earlier quoted context omitted.
Amazing yes. But I think that on certain sections they should output the console value instead. I'm specific talking about the Array Spread example as the Babel output in that case is a very roundabout and verbose way of showing me what the Array Spread Operator actually does. I think it would be better to allow the user to play with the operator and see the output of it right next to the code.
Totally agree with you on that. When I have a little more time I'm gonna add that. The compiled output starts out awesome with the first few sections, and then just gets tedious and weird.
perhaps add the compiled option as a toggle button instead of an always on thing and have the log output be the main attraction.

#53Small nit pick. Realm does not use the "underlying SQLite database" as listed here: http://www.reactnativeexpress.com/persistence . Realm is built from scratch as an append only database, see here: https://realm.io/products/realm-mobile-database/ and here: https://github.com/realm/realm-core .
How would you compare Realm vs Couchbase Mobile in terms of a syncing mobile store? Maybe a more fair comparison is to IBM's CloudantSync[0] which is the managed service version of Couchbase compliant Cloudant. [0] https://developer.ibm.com/clouddataservices/offline-first/
(Adam from Realm) Realm is an ACID compliant object database. Compared to Couchbase it is much more performant and memory efficient. In terms of data sync, Realm works by transferring the compressed changes from the transaction log (so just the diffs and capturing the semantic intent of the action) and automatically resolving conflicts using operational transformation. This approaches leads to extremely low latency enabling realtime collaboration functionality. This is quite different than Couchbase which is sending the entire object, requiring the developer to manually resolve conflicts.
