Why are objects encapsulated?

So that they can act as templates for other objects

To create an interface for an app

To share their code in a prototype chain

So that the code and data are hidden from other programs

What is an object literal?

A template for the creation of other objects

A native object built into JavaScript

A host object used by the web browser

A standalone object used for a single purpose

Provide the reference to the dateHired property of the employee object in bracket notation.

employee.dateHired

employee$[$dateHired$]$

employee$["$dateHired$"]$

employee:dateHired

The new Object$()$ command $\_\_\_\_\_\_\_\_\_\_\_\_.$

creates a new object from the JavaScript base object

is used to create an object class

is used to create a closure

creates a new native object

An object class is used $\_\_\_\_\_\_\_\_\_\_\_\_.$

to create standalone objects built for a single purpose

to create native objects

as a template for new objects sharing the same properties and methods

to create host objects

To create an object class, you need a$($n$)\_\_\_\_\_\_\_\_\_\_.$

JavaScript framework

constructor function

object literal

closure

Provide code to instantiate an object from the Employee object class, storing the object in the myEmp variable.

let myEmp $=$ new Employee;

let myEmp $=$ Employee$()$;

let myEmp : Employee$()$;

let myEmp $=$ new Employee$()$

What is an object prototype?

A literal object used for a single purpose

A template for all properties and methods associated with an object class

A constructor function used to create an object class

A host object built into the web browser

Provide code to add the review$()$ method to the prototype of the Employee class.

Employee.review $=$ function$()$

Employee.prototype.review$()=$ function

Employee.prototype.review $=$ function

Employee.review.prototype $=$ function

A closure is a $\_\_\_\_\_\_\_\_\_\_\_\_.$

command block that encloses an object$$s properties and methods

copy of a variable that encloses that variable$$s value

closed chain of object prototypes

copy of a function along with the lexical environment of variables within that function

What is a privileged method?

A method that takes precedence over other methods in the script

A method created that access private variables and methods but is also accessible to the public

A method associated with an object prototype

A method associated with a native or host object

The hierarchy of objects connected via their prototypes is known as a$($n$)\_\_\_\_\_\_\_\_\_\_\_\_.$

prototype chain

prototype tree

object list

object tree

Which object method references the prototype of an object instance?

Object.prototype$()$

Object.getPrototype$()$

Object.getPrototypeOf$()$

Object.loadPrototype$()$

A for in loop is used to $\_\_\_\_\_\_\_\_\_\_\_\_.$

iterate through the contents of an associative array

determine whether an object contains a specified property

iterate through the contents of any array

write the contents of an object in JSON format

Which method should be used to convert text written in JSON to a JavaScript object?

JSON.toObject$()$

JSON.stringify$()$

JSON.construct$()$

JSON.parse$()$

What are some advantages of creating custom objects using object$-$oriented programming?

Provide code to create an object class named realEstate containing two properties named salesPrice and squareFoot, setting both of those property values to null.

Why should you add a method to the prototype of an object class rather than adding the method to the constructor function of the object class?

What are the advantages and disadvantages of closures?

Why would you place object data in the JSON format?
