1 - Explain the concept of data binding in AngularJS: Data binding allows the automatic synchronization of data between the application's view and model.
2) Describe the difference between $scope and $rootScope: $scope is used to manipulate data within a specific controller, while $rootScope is shared among all controllers and views.
3) What is the purpose of directives in AngularJS? Directives extend the HTML syntax, allowing you to create custom reusable components.
4) Explain the role of filters in AngularJS: Filters transform or format data before it's displayed in the view.
5) Describe the routing mechanism in AngularJS: Routing allows you to navigate between different views within the application.
6) What are services in AngularJS and how are they used? Services provide a way to share data and functionality across the application.
7) Explain the concept of controllers in AngularJS: Controllers serve as the bridge between the view and the model, handling user events and manipulating the data.
8) Describe the difference between factories and providers in AngularJS: Factories create a new instance of the service for each injection, while providers create a single instance that's shared across the application.
9) What is dependency injection in AngularJS and how does it work? Dependency injection allows you to inject dependencies into your components, simplifying development and testing.
10) Explain the purpose of the $location service in AngularJS: $location provides access to the current URL and allows you to manipulate it.
11 - Describe the difference between $watch and $digest in AngularJS: $watch monitors a specific expression for changes, while $digest triggers a full evaluation of the application's bindings.
12) Explain the concept of unit testing in AngularJS: Unit testing involves testing individual components or modules in isolation to ensure their functionality.
13) Describe the process of using mocking in AngularJS unit tests: Mocking allows you to create fake or virtual dependencies, making it easier to test specific components.
14) Explain the difference between shallow and deep watching: Shallow watching only observes the immediate properties of an object, while deep watching recursively monitors nested properties as well.
15) Describe the purpose of the $http service in AngularJS: $http provides a way to perform HTTP requests and handle server interactions.
16) Explain how asynchronous operations are handled in AngularJS: Asynchronous operations are executed outside the $digest cycle and their results are automatically incorporated into the application.
17) Describe the concept of service workers in AngularJS: Service workers are web workers that run separately from the main JavaScript thread and handle tasks like caching and offline support.
18) Explain the role of transclusion in AngularJS: Transclusion allows you to insert content into a directive's template from the surrounding HTML.
19) Describe the purpose of the ngModel directive in AngularJS: NgModel binds the value of a form element to a property on the $scope object.
20) Explain the concept of modules in AngularJS: Modules organize the application's components and allow you to group related functionality.
