What is AngularJS, and what are some of its signi몭cant advantages? 1. What is AngularJS, and what are some of its signi몭cant advantages? This is the 몭rst and foremost question you should ask while hiring an Angular JS developer that you know how well he is acquainted with Angular. hiring an Angular JS developer so AngularJS is a JavaScript MVC framework that enables you to build dynamic, robust, and maintainable web applications. Some of its signi몭cant advantages include : AngularJS is built on the principle of MVC, which helps you to develop well-structured and layered web applications. It offers an extensive library of directives that allows you to create custom reusable components writing no additional code. The data binding feature between the model and view ensures that it simultaneously re몭ects any changes made in the view in the model and vice versa. This eliminates the need for manual synchronization of data between different parts of your application. AngularJS is very well-documented, with a large community of supporters who are always willing to help.

3. It provides several out-of-the-box features, saving developers time and effort in developing their applications. 2. What are the DOM and the BOM? 2. What are the DOM and the BOM? DOM, also known as Document Object Model, is a platform and programming model for building user interfaces. BOM, also known as Browser Object Model, is a collection of objects that represent the state of the Document Object Model . Together, DOM and BOM allow developers to create dynamic web applications. AngularJS uses the DOM to manipulate the HTML document, while the BOM keeps track of the state of the DOM. This allows AngularJS to create a more e몭cient and responsive user interface. 3. What is dependency injection? 3. What is dependency injection? Dependency injection is a unique software design pattern that allows you to inject dependencies into objects rather than creating those objects with the dependencies. This makes it easier to test objects and change the dependencies if needed. AngularJS uses dependency injection to make it easier to create and use services. Services are objects that perform speci몭c tasks, such as handling HTTP requests or retrieving data from a database. DI allows you to inject a service into any object that needs it without creating the object speci몭cally for that service. This makes it easier to reuse services and test objects that use them. 4. What is a directive? 4. What is a directive? A directive is an AngularJS construct that allows you to add custom behavior to HTML elements or attributes. Directives are used to create reusable components and to extend the functionality of HTML. AngularJS has several built-in directives, such as ng-app, ng-model, and ng-repeat. You can also create your own directives to add custom behavior to your applications. 5. What is a service? 5. What is a service? A service is an object that performs a speci몭c task, such as handling HTTP requests or retrieving data from a database.

4. Services isolate business logic from the user interface and make it easier to reuse code. AngularJS uses dependency injection to make it easy to create and use services. You can inject a service into any object that needs it without creating the object speci몭cally for that service. This makes it easier to reuse services and test objects that use them. 6. What is the difference between a controller and a directive? 6. What is the difference between a controller and a directive? A controller is an AngularJS construct that allows you to control the behavior of your application. Directives are used to create reusable components and to extend the functionality of HTML. AngularJS has several built-in directives, such as ng-app, ng-model, and ng-repeat. You can also create your own directives to add custom behavior to your applications.

AngularJS is typically based on the Model View Controller (MVC) architectural pattern. The MVC pattern helps to organize and structure an application into three major components: the model, the view, and the controller. Moreover, the model represents the data and business logic of the application. The view displays the model data to the user and allows the user to interact with the data. The controller manages the interactions between the model and the view. 8. What is data binding in AngularJS? and How does it relate to the MVC architecture? 8. What is data binding in AngularJS? and How does it relate to the MVC architecture? It is the process of synchronizing data between the model and the view. In AngularJS, the $scope object handles data binding. The $scope object is an instance of the Scope class, which is a part of the AngularJS framework. The Scope class provides several methods that help to bind the model and the view. These methods include the $watch() and $apply() methods. The $watch() method watches for changes in the model data and updates the view accordingly. The $apply() method updates the view immediately, without waiting for a change in the model data. 9. Explain the concept of scope. How does scope inheritance work in AngularJS? 9. Explain the concept of scope. How does scope inheritance work in AngularJS?

5. Scope is an object that contains the model data and the view data. The scope is created automatically when you create an AngularJS application. It is attached to the DOM element that corresponds to the view. The scope object is a child of the $rootScope object. The $rootScope object is a global object that is created by the AngularJS framework. The $rootScope object contains several properties and methods that help to manage the scope hierarchy. The scope object can be extended to create new scopes. This is known as scope inheritance. The new scope inherits the properties and methods of the parent scope. However, it can also add its own properties and methods. Also Read: Also Read: Top 10 Advantages of Using AngularJS for App Development Top 10 Advantages of Using AngularJS for App Development 10. What is the signi몭cant difference between a directive and a 몭lter in AngularJS? 10. What is the signi몭cant difference between a directive and a 몭lter in AngularJS? The main difference between a directive and a 몭lter in AngularJS is that a directive executes code while a 몭lter formats data. Directives are typically used to add functionality to an application, while 몭lters are used to format data for display. Directives are registered with the $compileProvider, which means they get compiled and executed before the template is rendered. This allows directives to manipulate the DOM before it is displayed to the user. Because of this, directives have access to the entire scope object, which gives them more control over the application than 몭lters have. Filters are only executed when their input values change, meaning they aren’t run on initial page load like directives are. Because 몭lters don’t have access to the scope object, they are limited in the ways they can manipulate data. However, 몭lters are very useful for formatting data for display purposes. 11. Explain the difference between a factory and a service in AngularJS? 11. Explain the difference between a factory and a service in AngularJS? A factory in AngularJS is a function that creates objects. A service, on the other hand, is a function that retrieves data from a remote source. Factory functions are usually used to create objects that are not related to each other. For example, you might have a factory function that creates an object to represent a customer and another factory function that creates an object to represent order.

6. In this case, the customer and order objects would not be related to each other. Service functions, on the other hand, are usually used to retrieve data from a remote source. For example, you might have a service function that retrieves all of the customer information from a remote server. The service function would then return an object that represents the customer information. 12. What are the elemental parts of an Angular application? 12. What are the elemental parts of an Angular application? An Angular application is composed of several distinct parts: the root component, directives, services, and pipes. The root component is the entry point for your application. This component de몭nes the structure for your application and sets up the initial state. Directives are components that can be attached to other components to provide additional functionality. For example, a directive might be used to add animation or styling to a component. Services are used to provide isolated pieces of business logic that can be accessed by any other component in your application. Services are typically injected into directives or controllers using the dependency injection system. Pipes are used to transform data before it is displayed to the user. Pipes can be chained together to create complex data transformations. 13. Explain the role of $routeProvider in AngularJS.? 13. Explain the role of $routeProvider in AngularJS.? The $routeProvider is used to con몭gure the routing for an Angular application. The $routeProvider de몭nes the routes for the application and provides information about how to handle navigation between routes. When a user navigates to a new page in your application, the $routeProvider will determine which route to use and will invoke the associated controller and view. Moreover, the $routeProvider also provides a mechanism for con몭guring route parameters and retrieving data from the route.
