Inheritance takes all the functionality from a parent class and allows you to add more. A class can inherit all the methods and properties of another class by using class inheritance. Inheritance has code reusability features.
We can also implement inheritance to make the child inherit all Parent Class methods. This can be done by the extends and super keywords. The extends keyword has been implemented for inheritance in ES6. The child class is extended to call a base class or parent class. It is called a derived class or child class. In the constructor, the super() method is used to access all parent properties and methods the derived class uses. ES6 Javascript supports the concept of inheritance. Inheritance is the ability to create new entities from an existing entity. The class extended to create newer classes is called the parent or super class. The new classes are known as the child or sub-classes. Child classes inherit all properties and methods from the parent class except constructors.
The syntax for the inheritance:
class child_class_name extends parent_class_name
Types of Inheritance:
- Single-level inheritance - an inheritance in which the child class can only inherit the properties from one parent class
- Multiple inheritances - an inheritance in which a class can inherit the properties from the various classes. ES6 doesn’t support multiple inheritances.
- Multi-level inheritance is an inheritance in which a child class inherits the properties from another child class, inherits from the parent class, and so on.
Here is an example of how to do ES6 Javascript Inheritance:

I found this code snippet by searching for ' ES6 javascript inheritance ' in kandi. You can try any such use case!
Environment Tested
I tested this solution in the following versions. Be mindful of changes when working with other versions.
- The solution is created in VS Code 1.73.1 version.
- JavaScript (ES6) code snippets v1.8.0
- Code Runner v0.12.0
Using this solution, we are able to do ES6 javascript inheritance with simple steps. This process also facilities an easy way to use, hassle-free method to create a hands-on working version of code which would help us to do ES6 javascript inheritance.
