1 - What is the difference between a directive and a component in AngularJS?
Answer: Directives are used to extend the HTML syntax and add behavior to DOM elements, while components are self contained modules with their own template, styles, and logic.
2) Explain dependency injection in AngularJS.
Answer: Dependency injection is a mechanism for automatically providing dependencies to a function or class. This makes it easier to test and maintain code.
3) What is the purpose of the $scope object in AngularJS?
Answer: The $scope object is a bridge between the controller and the view. It allows the controller to share data with the view and to handle events from the view.
4) Explain the difference between One way and Two way data binding in AngularJS.
Answer: With one way data binding, the model changes whenever the view changes. With two way data binding, both the model and the view are updated whenever either the model or the view changes.
5) What is the purpose of filters in AngularJS?
Answer: Filters are used to transform the data before it is displayed in the view. They can be used to format dates, numbers, strings, and more.
6) Explain the role of the ng repeat directive in AngularJS.
Answer: The ng repeat directive repeats a section of HTML for each item in a collection. This makes it easy to create lists, tables, and other repeated content.
7) What is the difference between a service and a factory in AngularJS?
Answer: Services are singletons, while factories are not. This means that services are only instantiated once, while factories are instantiated every time they are used.
8) Explain the purpose of the $http service in AngularJS.
Answer: The $http service is used to make requests to the server. It can be used to get, post, put, and delete data.
9) What is the difference between a promise and a callback in AngularJS?
Answer: Promises are asynchronous operations that represent a future value. Callbacks are functions that are called when an asynchronous operation completes.
10) Explain the purpose of the ng model directive in AngularJS.
Answer: The ng model directive binds a form input to a model property. This allows the model property to be updated when the user changes the input.
11 - What is the difference between a controller and a service in AngularJS?
Answer: Controllers are responsible for managing the behavior of a view. Services are responsible for providing reusable functionality to the application.
12) Explain the purpose of the ng init directive in AngularJS.
Answer: The ng init directive initializes the model of a controller. This can be used to set default values for the model.
13) What is the difference between a template and a view in AngularJS?
Answer: Templates are HTML files that are used to define the structure of a view. Views are instantiated from templates and are responsible for displaying data to the user.
14) Explain the purpose of the $timeout service in AngularJS.
Answer: The $timeout service is used to schedule functions to be executed after a specified delay. This can be used to create animations, delays, and other time based effects.
15) What is the difference between a directive and a filter in AngularJS?
Answer: Directives are used to change the behavior of DOM elements, while filters are used to transform data.
