Directives in
angular are special notations which allows us to extend the behavior of DOM
elements in the view template. For example the ngFor is a built-in Angular directives, the ngFor directive is used
to repeat a set of HTML elements for a predefined number of times thereby
creating a table/list structure in the view template.
Directives are not totally new to the Angular world, we had directives like ng-repeat in AngularJS which did the same thing as ngFor. Since Angular has evolved from AngularJS, the Directives structure and templates have also evolved with it since Angular 2+
Directives are classes declared using @Directive. Directives also have different life-cycle hooks which we can implement to alter the behavior of the Directives.
A new directive can be created using the following CLI command.
ng generate directive
