Three Pillars of Web Application Development

The three pillars of web application development are the front-end, the back-end, and the data store. We covered each of these areas with a single technology choice for each one. We also covered documenting a program, working with the pieces interactively, and testing both with unit tests and snapshot tests. We also learned how to handle authentication and accounts without resorting to a complicated library or a bloated framework. Lastly, we learned how to deploy the application to the internet to make it available worldwide using a free tier of service from Heroku.
