In this tutorial, we will be discussing how to use the CanDeactivate guard in an Angular application. The CanDeactivate guard is used to prevent a user from navigating away from a route if there are unsaved changes in a form. This can be useful for situations where a user is filling out a form and accidentally navigates away from the page, potentially losing their progress.
We will be using a student profile form as an example to show how to implement the CanDeactivate guard in an Angular application.
