2) What are the key features of Angular 1.5?
Improved performance, better two way data binding, and integrated routing.
3) Explain the concept of modules in Angular 1.5.
Modules encapsulate related components and services, promoting code organization and maintainability.
4) Describe the lifecycle of an AngularJS directive.
Directives have three phases: compile, link, and post link.
5) What is the role of $scope in Angular 1.5?
$scope provides a model for data binding between the controller and the view.
6) Explain how to use AngularJS filters.
Filters transform data before displaying it in the view.
7) How does Angular 1.5 handle dependency injection?
Dependency injection allows components to be easily reused by passing their dependencies as arguments.
8) What are services in Angular 1.5?
Services provide reusable functionality that can be shared across the application.
9) Describe the use case for the $http service.
$http simplifies sending and receiving HTTP requests.
10) Explain how to use the $routeProvider to configure routing in Angular 1.5.
$routeProvider allows for declarative routing configuration.
11 - How does Angular 1.5 handle asynchronous operations?
AngularJS uses promises to handle asynchronous operations, allowing for code to be executed after a request completes.
12) What are the advantages of using AngularJS testing frameworks?
Testing frameworks help improve test coverage, reliability, and maintainability.
13) Describe the purpose of the AngularJS ng repeat directive.
ng repeat creates a list of elements based on an array or collection.
14) Explain the difference between ng model and ng bind.
ng model binds the value of a form control to a model, while ng bind binds the value of a model to the DOM.
15) How do you handle form validation in Angular 1.5?
AngularJS provides built in validation directives and services for handling form validation.
