Inheritance is an important concept in Object-Oriented Programming that allows one class to use the properties and methods of another class.
Instead of writing the same code again and again, you can create a base class and reuse its features in other classes.
Inheritance helps reduce code duplication and makes programs easier to maintain and extend.
Why Use Inheritance
- Reuses existing code
- Reduces duplication
- Makes programs easier to extend
- Keeps code organized
- Follows professional coding standards
Inheritance is widely used in real-world applications.
This is a base class that contains common properties and methods.
Other classes can inherit from this class.
The Student class inherits from the Person class using the extends keyword.
The super() method calls the constructor of the parent class.
These examples show how inheritance allows classes to share common behavior.
By mastering inheritance, students gain the ability to build scalable and well-structured JavaScript applications using professional OOP techniques.
