Question 6

MVC

Answer 6

Model View Controller

Question 7

Three parts of the MVC:

Answer 7

-model
-view
-controller

Question 8

the model

Answer 8

The model represents the underlying, logical structure of data in a software application.

Question 9

the view

Answer 9

view is the body of code that represents the user interface (all of the things that the user can see
and to which the user can respond on the screen, such as buttons, dialog boxes, and so on).

Question 10

the controller

Answer 10

• The controller element refers to the software code that works with application logic to complete a
  task. Moreover, the controller is key to maintaining the communication between the model and
  view elements.
• i.e., the controller acts as the intermediary between the view and the model.
• the controller keeps the model and the view separated—one has no direct knowledge of the
  other.

Question 11

scope

Answer 11

• Scope in AngularJS is the binding part
  between HTML (view) and JavaScript
  (controller) and it is a built-in object.
• It contains application data and objects
• It is available for both the view and the
  controller.

Question 12

Filters

Answer 12

• When working with data that has been retrieved
  from a database, we need to spend a lot of time
  working with raw unformatted data.
• When presenting data to end users, however, we
  need a way to deal with such things.
• Angular JS filters are often a very good way to deal
  with that.

Question 13

AngularJS filters

Answer 13

AngularJS filters format the value of an
expression for display to the end user.
– They don’t actually change the underlying data,
but they change how it is displayed in the
particular case in which the filter is applied.

Question 14

Built-in Filters

Answer 14

The filters are kept inside the expressions
– Number Filter - number
– Date Filter - date
– limitTo Filter - limitTo
