Directives in AngularJS are markers on DOM elements (attributes, elements, comments) that tell AngularJS's HTML compiler ($compile) to attach a specified behavior. They extend HTML functionality. Examples are ng-app, ng-model, ng-repeat, etc.
<!DOCTYPE html> <html ng-app="myApp"> <head><title>ng-app Example</title></head> <body> <h1>AngularJS App Example</h1> </body> </html>

<script>
var app = angular.module("myApp", []);
app.controller("myCtrl", function($scope){
$scope.message = "Hello from ng-bind!";
});
