TypeScript for Beginners - Inheriting Functionality

What is the primary benefit of using inheritance in programming?

• It prevents any changes to the parent class.

• It ensures that all classes have the same methods.

• It enables child classes to inherit and reuse common functionalities from a parent class.

• It allows for the creation of multiple instances of a class.
