Angular Interview Practice

In Angular, guards are primarily used for controlling navigation based on specific conditions. This includes determining whether a user can access a particular route or whether they need to be redirected elsewhere. The types of guards available in Angular, such as CanActivate, CanDeactivate, Resolve, and CanLoad, allow developers to manage route access based on logic like authentication status, role permissions, or any other conditions relevant to the application’s flow.

For instance, a CanActivate guard can check if a user is logged in before allowing access to a specific route. If the conditions are not met, the guard can redirect the user or display an error message, thus enhancing the security and user experience of the application.

Contexts like defining styles of components, providing data to components, or implementing lazy loading do not relate to the purpose of guards. Guards focus specifically on the conditions under which routing can occur, which is crucial for maintaining controlled navigation within an Angular application.
