AngularJS provides a built-in angular.isFunction() function that can be used to determine if a value is a function or not.

Here's an example of how to use the angular.isFunction() function:

angular.module('myApp', [])
  .controller('myController', function($scope) {
    $scope.myFunction = function() {
      console.log('Hello, world!');
    };

    var myValue = 'hello';

    if (angular.isFunction($scope.myFunction)) {
      $scope.myFunction(); // prints 'Hello, world!' to the console
    }

    if (angular.isFunction(myValue)) {
      console.log('This is a function!');
    } else {
      console.log('This is not a function!');
    }
  });

In this example, we define a function called myFunction on the $scope object of an AngularJS controller. We then use the angular.isFunction() function to check if myFunction is a function. Since myFunction is indeed a function, we call it using the $scope object.

We also define a variable called myValue that contains a string value. We then use the angular.isFunction() function to check if myValue is a function. Since myValue is not a function, we log a message to the console indicating that it is not a function.

The angular.isFunction() function can be useful when working with dynamic data in AngularJS, as it allows you to determine if a value is a function before attempting to call it. This can help prevent errors in your application.
