Angular Directives

In Angular, Directives are good features for re-usability.

-Directives are used for reusable purpose for example Time Picker Controller, Data Picker Controller, File Upload Controller as well as any kind of custom logic and custom validation to control that as required by the program.

-Directives are like user control in ASP.NET Web Pages and HTML extension in ASP.NET MVC applications.

-Keep in mind that if you are creating Directive for reusable purpose then it should not use the scope of any controller and should work independent of scope or controller.

-Don’t write any Directive name starting with ng- as it may create the conflict with Angular directives also can generate the ambiguity.
