It highlights the flexibility of the latest class syntax, including private and static members, and demonstrates the use of classes as expressions. The tutorial concludes with a discussion on inheritance syntax, encouraging learners to continue exploring JavaScript.

What is the primary purpose of destructuring in JavaScript?

• To define new classes

• To create new objects

• To simplify the extraction of values from arrays or objects

• To implement inheritance

Which of the following is a key feature of the latest class syntax in JavaScript?

How does the new class syntax compare to other object creation methods?

• It is deprecated

• It is more flexible

• It is less flexible

• It is the same in terms of flexibility

What is a benefit of using classes as expressions in JavaScript?

• They can be used as standalone functions

• They simplify the syntax for loops

• They allow for dynamic inheritance

• They enable encapsulation of logic

What is a significant change in the new inheritance syntax in JavaScript?

• It allows for multiple parent classes
