    1. The section of code with exports.app = functions.https.onRequest(app); exposes your express application so that it can be accessed. If you don't have the exports section, your application won't start correctly
    2. Firebase Functions enables you to use the ExpressJS library to host a Serverless API. Serverless is just a term for a system that runs without physical servers. This is a bit of a misnomer because it technically does run on a server, however, you’re letting the provider handle the hosting aspect

    1. To return data after an asynchronous operation, return a promise.

      I just struggled for a few hours trying to resolve some errors about CORS and 500 INTERNAL errors.

      This line is a bit misleading.

      In trying to get things up and running, I was returning a simple JSON object rather than a Promise. According to what I found, even if you don't have any async work, you still need to return a Promise from your function.
