We need to ensure each environment is configured correctly, it could be disastrous if our production application was using our development database, for example. Environment variables allow us to manage the configuration of our applications separate from our codebase. Separate configurations make it easier for our application to be deployed in different environments. Environment variables are variables external to our application which reside in the OS or where the container of the app is running in.
