Sample Practice Test Questions

Question 1: Understanding MVC Architecture

What is the primary purpose of the Model-View-Controller (MVC) architecture in AngularJS?

a) To separate the user interface logic from business logic
b) To enhance the security of the application
c) To increase the speed of the application
d) To enable real-time data binding

Correct Answer: a) To separate the user interface logic from business logic

Explanation: The Model-View-Controller (MVC) architecture is a software design pattern that separates an application into three main logical components: the Model, the View, and the Controller. Each of these components is built to handle specific development aspects of an application.

• Model: This represents the application's data and business logic. It is responsible for managing data, responding to requests for information, and providing the necessary data to the controller or view when required.

• View: This component is responsible for displaying the data provided by the model in a specific format. In the context of AngularJS, the view is typically composed of HTML templates and AngularJS directives.

• Controller: The controller acts as an intermediary between the model and the view. It processes user input, manipulates data from the model, and updates the view accordingly.

By separating these concerns, MVC architecture helps in organizing code better, making it more manageable, maintainable, and testable. This separation of concerns also facilitates parallel development, where different team members can work on the model, view, and controller independently. Additionally, it improves the scalability of the application by making it easier to update or change any component without affecting the others.

Question 2: Two-Way Data Binding

How does two-way data binding benefit an AngularJS application?

a) It enhances the application's performance by reducing server requests
b) It allows automatic synchronization of data between the model and the view
c) It prevents security vulnerabilities by restricting data flow
d) It simplifies routing and navigation within the application

Correct Answer: b) It allows automatic synchronization of data between the model and the view

Explanation: Two-way data binding is one of the most powerful features of AngularJS, allowing automatic synchronization of data between the model (JavaScript objects) and the view (HTML templates). Here’s how it works:

• Automatic Updates: Any changes made to the model are instantly reflected in the view, and vice versa. This means that when a user updates the input field (view), the underlying model data is immediately updated without any additional code.

• Simplified Code: This mechanism reduces the amount of boilerplate code needed to manually track and update data. In traditional applications, developers often have to write code to update the view when the model changes and update the model when the view changes, leading to potential bugs and increased complexity.

• User Experience: Two-way data binding enhances the user experience by providing real-time updates. For example, in a form, as users type into input fields, they can see changes immediately reflected elsewhere in the application, providing a dynamic and interactive experience.

While two-way data binding simplifies development and improves the user experience, it’s important to note that it can also have performance implications, especially in large-scale applications with a lot of binding expressions. To mitigate this, AngularJS provides mechanisms like one-time binding and track-by options to optimize performance when necessary.

Question 3: Directives and Their Types

Which of the following is an example of a built-in AngularJS directive?

a) ng-router
b) ng-model
c) ng-websocket
d) ng-express

Correct Answer: b) ng-model

Explanation: AngularJS directives are special tokens in the markup that tell the library to do something to a DOM element (e g, hide it, show it, attach a behavior). Directives are an essential part of AngularJS, extending the HTML vocabulary and creating reusable components. Some commonly used built-in directives include:

• ng-model: This directive binds the value of HTML controls (input, select, textarea) to application data. It provides two-way data binding, updating the view whenever the model changes and vice versa. For example, <input type="text" ng-model="userName"> binds the input field to the userName model.

• ng-repeat: This directive repeats a set of HTML elements for each item in a collection. For example, <div ng-repeat="item in items">{{ item . name }}</div> would repeat the div element for each item in the items array.

• ng-if: This directive conditionally includes or excludes a portion of the DOM based on the expression's truthiness. For example, <div ng-if="isVisible">This will be shown if isVisible is true</div> includes the div element if isVisible is true.

• ng-class: This directive dynamically binds one or more CSS classes to an element based on an expression. For example, <div ng-class="{active: isActive}"> adds the active class to the div if isActive is true.

Directives like ng-router and ng-websocket do not exist in AngularJS; instead, routing is typically handled by ngRoute or ui-router, and web socket functionality would be implemented through custom services or third-party libraries.
