Q:

When do we use a directive in Angular?

Answer 1

If you create an Angular application where multiple components need to have similar functionalities, you have to do it by adding this functionality individually to every component. This is not a very easy task. Directives are used to cope up with this situation. Here, we can create a directive with the required functionality and then import the directive to components that require this functionality.
