Return Value: It returns true if the value passed is a function else false.

<!DOCTYPE html>
<html>
  
<head>
    <script src=
"//ajax.googleapis.com/ajax/libs/angularjs/1.3.2/angular.min.js">
    </script>
    <title> angular.isFunction() </title>
</head>
  
<body ng-app="app" 
      style="text-align:center">
    <h1 style="color:green">
        GeeksforGeeks
    </h1>
    <h2>angular.isFunction()</h2>
    <div ng-controller="geek">
        <b>Input1: </b>
        <span>
            <code>
                obj = [{ name: "Abc"}, { name: "Xyz"}];
            </code>
        </span><br
        <b>IsFunction: </b> {{isFunction1}}<br />
        <br><br
        <b>Input2: </b
        <code>
            var Add = function () {
                return null;
            };
        </code><br>
        <b>IsFunction:</b> {{isFunction2}}
    </div>
    <script>
        var app = angular.module("app", []);
        app.controller('geek', ['$scope', function($scope) {
            var obj = [{
                name: "Abc"
            }, {
                name: "Xyz"
            }];
            var Add = function() {
                return null;
            };
            $scope.isFunction1 = angular.isFunction(obj);
            $scope.isFunction2 = angular.isFunction(Add);
        }]);
    </script>
</body>
