Now that we have added a second application to our Angular CLI config, we need to make sure we can easily build both applications without having to memorize the exact commands.

In order to do so, we will leverage the so-called npm scripts. These scripts are used to define operations that can be performed on our application. Examples of these operations are building the application, running tests, and deploying the application to a staging or production environment.

To get an idea of how these scripts work, consider the following flow:
