Web application vs website in Laravel, what is the difference?

A website is mostly informational with limited interactivity. A web application has logged in users, data that persists, business logic, and workflows. Both can be built with Laravel, but a web application uses Laravel's full strength (authentication, authorisation, database modelling, queues, events, real time, testing) while a website often runs on a much lighter setup. If you log in, perform actions, and the system remembers state, you are looking at a web application.
