TS Inheritance
Class Inheritance
TypeScript inheritance extends classes with override for methods.
What is Inheritance in TypeScript?
Inheritance in TypeScript is a mechanism that allows a class to inherit properties and methods from another class. This helps in reusing code and establishing a hierarchical relationship between classes. In TypeScript, inheritance is implemented using the extends
keyword.
Basic Inheritance Example
Let's start with a simple example to demonstrate how a class can inherit properties and methods from another class in TypeScript.
Overriding Methods
One of the key features of inheritance is the ability to override methods. This allows a subclass to provide a specific implementation of a method that is already defined in its superclass.
Using the Super Keyword
The super
keyword is used to access and call functions on an object's parent class. This is particularly useful when you need to extend or modify the behavior of an inherited method.
Conclusion
Inheritance in TypeScript provides a powerful way to build object-oriented applications with reusable and extendable code. By using the extends
keyword, developers can create complex systems with ease, leveraging both inherited and overridden methods to achieve desired functionality.
In the next section of this series, we will explore Abstract Classes, which further enhance the capabilities of TypeScript's class-based programming.
