Modern JavaScript from the Beginning - Second Edition - Getters and Setters with Classes

The video tutorial explains the use of getters and setters in JavaScript, focusing on their application within classes. It covers the creation of a class with private properties, the implementation of getters and setters to manipulate these properties, and the use of helper functions to optimize code. The tutorial also demonstrates how to combine properties using getters, providing practical examples throughout.

What is one reason to use getters instead of directly accessing a property?

• To add functionality like formatting before returning the value

• To make the code run faster

• To ensure the property value is always lowercase

• To prevent the property from being deleted

In the context of classes, what is a constructor used for?

• To create a new class

• To initialize object properties

• To define methods for the class

• To delete object properties

Why might you use an underscore before a property name in JavaScript?

• To indicate the property is public

• To ensure the property is always a string

• To signify the property is private

• To make the property read-only

What problem can occur if a getter and a property have the same name?

• The getter will not be called

• The property will be deleted

• The property will become undefined

• Recursion may occur

What is the primary purpose of a setter in JavaScript?

• To modify a property value

• To create a new object

• To retrieve a property value

• To delete a property

How can you avoid repeating code when using setters for multiple properties?

• By using a different programming language

• By using global variables

• By creating a utility function

• By writing the code in a loop

What is a benefit of using a getter for a full name property?

• It allows the full name to be stored in the database

• It combines first and last names without storing them as a separate property

• It makes the full name immutable

• It automatically translates the name into multiple languages
