Explain important directories used in a common Laravel application.

Directories used in a common Laravel application are:

• App/: This is a source folder where our application code lives. All controllers, policies, and models are inside this folder.
• Config/: Holds the app’s configuration files. These are usually not modified directly but instead, rely on the values set up in the .env (environment) file at the root of the app.
• Database/: Houses the database files, including migrations, seeds, and test factories.
• Public/: Publicly accessible folder holding compiled assets and of course an index.php file.
