Environment Variables
Environment variables or (env variables) are values set outside of your application. They are usually used for configuring things inside your app. You can e.g. use them to securely store your API keys locally and still use public source control (GitHub for example) without exposing them.
Environment variable names are usually in all caps and words are separated with underscores. Example: MY_API_KEY.
Use the built-in object env to work with environment variables.
