By the end of this article, you will have a better understanding of the purpose of super() and how to best incorporate it into your React.js project to maximize productivity and efficiency.


Super() in React.js is an important concept for developers to grasp. It is a way for developers to access and utilize the parent class methods and properties when creating a class. It is used to invoke the parent class constructor, which helps developers set up a construction framework for their own subclass.
Class is the building block of an application, which consists of variables and methods known as properties and functions. These properties and functions are the foundation of the application’s code. This code is organized into data structures such as classes, objects, and modules for better organization and code reusability.
Constructor is a special method used to initialize a class. The constructor is used to create an instance of a class and assign values to its members. In React.js, the constructor can also be used to extend a parent class and invoke the parent’s constructor, which sets up the initial state of the subclass instance.
Subclass is a class that extends from a parent class. Subclasses are used to add new features and methods to an application without having to rewrite the entire code. It is a specialized class that inherits all its parent class properties and functions and can add any additional features that the parent doesn’t offer.
Super() is a built-in member of the JavaScript language and in terms of React.js it is used to invoke the parent class constructors. The super keyword is solely used in constructors to extend a parent’s class constructors. It establishes the framework of the class by calling the parent’s constructor and allowing the developer to build off of the parent’s class as a foundation.

Content Overview

Super() is an important tool in React.js for ensuring that a component’s behavior is properly inherited from React’s base class, the Component class. It is used to call the constructor of a parent class, allowing the child class to access instance variables and methods inherited from the parent class. Super() also allows newly defined versions of methods to access the parent method, and any changes to the parent method will be available in the child class.

What is Super()?

Super() is a method that comes with React’s Component class that allows a class to access and use the methods and instance variables of the parent class. This is useful for passing information to the child class from the parent. Additionally, it allows the child class to override the parent’s methods and to access them from within the child class.

What Are Its Benefits?

Using super() offers several benefits in React.js, including:

  • It allows the child class to access methods and instance variables from the parent class, which can be useful for retrieving data and reusing code.
  • It allows the child class to override methods from the parent class without the need to duplicate code.
  • It allows the child class to access the parent class’ methods without the need to do any extra work. This can be especially helpful when making global updates.
  • It ensures that the child class is properly extending the parent’s behavior.
  • It allows the child class to take advantage of new features added to the parent’s class since the parent was created.

When used correctly, super() can be an invaluable tool for writing cleaner, more maintainable React code. For example, classes can be extended quickly and easily with super(), instead of duplicating code or manually rewriting methods. Also, the parent class can be updated without having to make changes in multiple places if the parent methods are called using super().
When writing React components that extend React’s Component class, understanding super() and how to make use of it is essential for creating components that are easy to maintain and expand upon.

What is React.js?

React.js is an open-source JavaScript library developed by Facebook and used for building user interfaces and web applications. It enables developers to quickly create dynamic user interfaces with ease thanks to its reactive programming model and component-based approach. The library provides a set of core components which are reusable, modular, and easy to assemble.

Better Performance

One of the major advantages of React.js is its improved performance. It uses the virtual DOM to render its components, which makes it faster and more efficient than other libraries. This enables developers to create more interactive web applications in a shorter amount of time. Additionally, React.js optimizes DOM updates to reduce processing time. This helps the overall performance of the web application, as the DOM is a critical part of the rendering process.

Flexible and Scalable

React.js is very flexible and scalable, and is suitable for both small and large-scale projects. The library is extremely versatile, allowing developers to create cross-platform and mobile applications with great ease. It also supports the introduction of new features without needing to rewrite existing code. Furthermore, React.js has an extensive library of components that can be used to rapidly create user interfaces.
The empowerment of developers with React.js also relies upon the utilization of super() method. Super() method facilitates the developers to access and invoke the parent class methods and apply the same on the child class content when using the concept of inheritance. This helps developers to avoid writing long and complex JavaScript codes, by simply calling the parent method in the child class. Doing this leads to a better organized code which lets developers to debug and edit the application much more easily.

Understanding the Benefits of Using Super() in React.js

What is Super()?

Super() is a special keyword used in React to call the base constructor from derived constructors. This allows the derived constructors to inherit all the properties and functionalities of the base constructor. Super() facilitates the reuse of code from a base class, which can eliminate the need to repeat the same code on derived classes. Super() is also commonly used to initialize state in the constructor of a React component.

The Benefits of Super()

Using super() simplifies the readability of code, as much of the base code can be inherited by the use of the keyword. This can help anyone with lower technical abilities understand the code, as it assumes that they know the base structure of the React component’s parent. The child component can also benefit from larger code bases, as the code can more easily be adapted for more complex usage. Super() can also be useful when dealing with updates to the React component. If the base class is updated, it is not necessary to adjust the derived components, as they make use of the updated parent.
In addition to simplifying the readability and making code updates easier, super() can increase the maintainability of a codebase. By having the majority of the code stored in the parent component any minor changes that need to be implemented can be done easier. Rather than having to meticulously search through code and make individual changes, the Super() keyword allows for the entire parent to be updated and then inherited by the children. This can save time and help build more reliable codebases.
Overall, the Super() keyword can be used to increase the maintainability, readability, and reusability of code within a React application. It simplifies the process of implementing new changes to older code and reduces the possibility of introducing errors when making these changes. Super() is the perfect solution for anyone looking for a way to make their React code more organized and easier to maintain.
