Question 1

AngularJS is a library?
A)True
B)False
C)none
D)all

Accepted Answer

AngularJS is not a library; it is a framework used for developing single-page web applications.

Question 2

Who is sometimes called as Father of AngularJS?
A)Brad Green
B)Igor Minor
C)Misko Hevery
D)Brian Ford

Accepted Answer

Misko Hevery is widely recognized as the father of AngularJS due to his significant contributions to the initial development of the framework.

Question 3

Which of the following is true about ng-init directive?
A)ng-init directive initializes an AngularJS Application data.
B)ng-init directive is used to put values to the variables to be used in the application.
C)Both of the above.
D)None of the above.

Accepted Answer

The ng-init directive in AngularJS is used for both initializing application data and assigning values to variables within the application. It serves as a way to initialize data directly within the HTML, although its use for complex initializations is generally discouraged in favor of doing so within controllers or modules.

Question 4

Which of the following directive is used to initialize an angular app?
A)ng-model
B)ng-app
C)ng-controller
D)None of the above

Accepted Answer

The ng-app directive is used to initialize an AngularJS application. It designates the root element of the application and is typically placed in the root element of the HTML document.

Question 5

ng-app directive defines and links an AngularJS application to HTML.
A)false
B)true
C)none
D)all

Accepted Answer

The ng-app directive in AngularJS is used to define an AngularJS application. It designates the root element of the application and automatically initializes the AngularJS framework when the web page containing the directive is loaded.

Question 6

AngularJS supports two-way data binding?
A)True
B)False
C)none
D)all

Accepted Answer

AngularJS supports two-way data binding, allowing automatic synchronization of data between the model and the view components.

Question 7

AngularJS expressions are written using.
A)double braces like {{ expression}}
B)single braces like {expression}
C)small bracket like (expression)
D)capital bracket like [expression]

Accepted Answer

AngularJS expressions are written using double braces like {{ expression }}. This syntax is used to bind data to HTML, similar to how template systems work.

Question 8

AngularJS is an MVC based framework?
A)True
B)False
C)none
D)all

Accepted Answer

AngularJS is indeed an MVC (Model-View-Controller) based framework, which helps in organizing web applications by separating the logic, presentation, and data components.

Question 9

AngularJS bootstraps itself during config phase.
A)true
B)false
C)none
D)all

Accepted Answer

AngularJS bootstraps itself during the config phase because it is during this phase that the application's modules and components are registered and configured.

Question 10

Angular initializes based upon which of the following scenario?
A)DOMContentLoaded event happens
B)document.readyState is set to complete
C)Both of the above
D)None of the above

Accepted Answer

Angular initializes when either the DOMContentLoaded event fires or when the document.readyState is set to complete, indicating that the document is fully parsed and loaded.

Question 11

An Angular application can be initialized on ______?
A)Only HTML element
B)ANY element
C)none
D)all

Accepted Answer

An Angular application can be initialized on any element within the HTML. This is done by specifying the Angular module that should be bootstrapped for that element, allowing for a flexible integration of Angular into various parts of a web page or even within a larger application.

Question 12

Can an HTML page have multiple "ng-app" directive for bootstrapping multiple AngularJS application?
A)Yes
B)No
C)none
D)all

Accepted Answer

AngularJS does not support bootstrapping multiple applications on a single HTML page using multiple "ng-app" directives. Only one AngularJS application can be auto-bootstrapped per HTML document. Additional applications require manual bootstrapping.

Question 13

With more than one ng-app in an HTML document (an HTML page), are all of them automatically initialized?
A)Yes
B)No
C)No, only one app is automatically initialized. Others have to manually initialized.
D)none of the above

Accepted Answer

AngularJS only automatically initializes the first ng-app found in the HTML document. Any additional ng-app directives will not be automatically initialized; they require manual initialization through AngularJS's manual bootstrapping process.

Question 14

Can angular applications (ng-app) be nested within each other?
A)Yes
B)No
C)none
D)all

Accepted Answer

Angular applications cannot be nested within each other because each AngularJS application is designed to be a single-page application and should be bootstrapped only once.

Question 15

What are various possible prefixes such as 'ng-' using which Angular directives (for example, ng-app) can be defined?
A)'ng-', 'data-ng-', 'ng:'
B)'ng-'
C)'ng-', 'data-ng-', 'ng:', 'x-ng-'
D)'ng-', 'data-ng-','x-ng-'

Accepted Answer

Angular allows the use of 'ng-', 'data-ng-', 'ng:', and 'x-ng-' prefixes for defining directives to make them HTML validator compliant.

Question 16

What are various possible ways in which angular application can be initialized?
A)On an element, one could either put simply the attribute such as (ng-app, data-ng-app, ng:app, x-ng-app)
B)Put the named attribute such as (ng-app='demoApp')
C)Both of the above
D)none

Accepted Answer

Angular applications can be initialized in various ways, including using different forms of the ng-app attribute (such as ng-app, data-ng-app, ng:app, x-ng-app) or by specifying a named application with the attribute (e.g., ng-app='demoApp'). Both methods are valid for initializing Angular applications.

Question 17

filter filter is applied to an expression using pipe character.
A)true
B)false
C)none
D)all

Accepted Answer

The filter filter is indeed applied to expressions using the pipe character in various programming and scripting contexts, such as in AngularJS, where it is used to filter an array based on a specified criterion.

Question 18

What angular function is used to manually start up an angular application?
A)angular.bootstrap
B)angular.element
C)angular.copy
D)None of the above

Accepted Answer

angular.bootstrap is the function used to manually start up an AngularJS application, allowing you to initialize your application without using the ng-app directive.

Question 19

Which components can be injected as a dependency in AngularJS?
A)Application Module
B)constant
C)value
D)factory

Accepted Answer

The answer of Which components can be injected as a...

Question 20

Can multiple angular applications be bootstrapped using same element??
A)Yes
B)No. An error is thrown such as 'App Already Bootstrapped with this Element'
C)none
D)all

Accepted Answer

Angular does not allow multiple applications to be bootstrapped on the same element. Attempting to do so will result in an error indicating that the element is already bootstrapped with an application.
