A toast is a notification message that pops up in a web application (or other user interface) like a “piece of toast” and then disappears.
This is a front-end concern, and so one that is typically used in React code.
Code bases from the 20-21 academic year used a library called
react-toast-notifications, but support for that library was discontinued.
Starting in W22, we are using https://fkhadra.github.io/react-toastify/introduction.
