- 5.JWT authentication is the de-facto authentication standard
- 6.Sockets allow us to transmit data and update UIs in real-time
- 7.Deploy a backend server to Heroku that can store and serve data for our frontends

In Module 3: Backend we will build a backend server that performs logic, stores and serves data to our frontends using the JavaScript server framework Express.js. Our backends will use relational (tabled-based) databases (aka SQL databases, pronounced "sequel") instead of the JSON-like databases we used with Firebase. Most companies use SQL databases for the majority of their use cases because SQL can be more structured has less potential for human error.
