$rootScope is the root scope of the application and is inherited by all other scopes.
2) What is the use of $http service in AngularJS:
$http service is used to make HTTP requests from the AngularJS application.
3) How can you implement routing in AngularJS:
Routing in AngularJS is implemented using the ngRoute module.
4) What is dependency injection in AngularJS:
Dependency injection is a design pattern that allows objects to request dependencies from a factory.
5) What are the different types of directives in AngularJS:
AngularJS provides three types of directives: attribute directives, element directives, and comment directives.
6) What is the use of ng repeat directive in AngularJS:
ng repeat directive is used to create loops in the template.
7) What is the use of ng model directive in AngularJS:
ng model directive is used to create a two way data binding between the view and the model.
8) How can you create reusable components in AngularJS:
Reusable components in AngularJS can be created using directives or services.
9) What is the purpose of ng controller in AngularJS:
ng controller directive is used to associate a controller to a DOM element.
10) How does AngularJS handle change detection:
AngularJS uses a dirty checking algorithm to detect changes in the model.
11 - What are the benefits of using AngularJS:
AngularJS provides a structured and maintainable approach to web development, promotes code reuse, enhances performance, and provides a robust ecosystem.
12) What are the limitations of AngularJS:
AngularJS can be verbose and complex for simple applications, its learning curve can be steep, and it may not be suitable for projects with high performance requirements.
13) How can you handle errors in AngularJS:
Errors in AngularJS can be handled using exception services such as $exceptionHandler.
14) What is the difference between linking and compiling in AngularJS:
Linking is the process of connecting the directive to the DOM, while compiling is the process of transforming the directive into a template function.
15) How can you use filters in AngularJS:
Filters in AngularJS are used to transform the data in the view.
