· Introduced types of directives :
a)
Component Directives: They
made components reusable by encapsulating logic in HTML, CSS, and
JavaScript.
b)
Decorator Directives: They
can be used to decorate elements (for example, Hiding/Showing elements by ng-hide/ng-show or
adding a tooltip).
c)
Template Directives: These
can turn HTML into a reusable template. The instantiating of this template and
its insertion into the DOM could be completely controlled by the directive
writer. Examples include ng-repeat and ng-if.
