AngularJS application mainly relies on controllers to control the flow of data in the application. A controller is defined using ng-controller directive. A controller is a JavaScript object containing attributes/properties and functions. Each controller accepts $scope as a parameter which refers to the application/module that controller is to control.
<div ng-app = "" ng-controller = "empController">
...
</div>
<script>
function empController($scope) {
$scope.emp = {
firstName: "aarif",
lastName: "mohammad",
fullName: function() {
var empObject;
empObject= $scope.emp;
return empObject.firstName + " " + empObject.lastName;
}
};
}
</script>
