Every business, product developer, support provider, or marketer requires a website or web application to engage with customers. Crafting an application from scratch is challenging, as it demands time and budget. 

Here comes the Frameworks that streamline the process, reducing timelines and costs. ReactJS, also referred to as React and React Native, is a well-liked framework that facilitates the creation of mobile and web applications. 

React is used to create mobile applications, whereas React Native creates online applications. These two technologies serve distinct purposes. Despite certain similarities, choosing one for a project requires a thorough understanding of both to make an informed choice. 

Understanding the differences between React.js and React Native is crucial for making informed decisions in mobile app development. In this post, you can see the details of React.js and React Native.

Understanding React.js

This JavaScript framework was created by Jordan Walke in 2011 with support from Facebook. The framework satisfied the requirement for an upscale, dynamic frontend that enhances user interactions.

It is mostly used to create web application fronts. Because it is built with the JavaScript library, the framework is optimized to satisfy the speed requirements. It also identified a distinct method of web page rendering.

Features of the React.js

1. Free and Open-Source

A fundamental driver of React’s popularity lies in its status as a free and open-source framework. This characteristic empowers the developer community with remarkable flexibility. The open-source nature ensures constant development, allowing anyone to modify it. 

This not only fosters innovation but also contributes to React’s future-proof nature. The open-source feature of React.js reduces the possibility of abandonment, ensuring ongoing support and improvement. 

React’s collaborative nature and accessibility underscore its position as a dynamic and enduring solution for web development, fostering a thriving ecosystem of innovation and community engagement.

2. Virtual DOM

React employs a Virtual Document Object Model (VDOM), a lightweight, in-memory representation of the actual DOM, to enhance the rendering efficiency of components. 

This programming concept maintains an ideal or ‘virtual’ UI representation in memory and synchronizes with the ‘real’ DOM through a library like React DOM. The mechanism of syncing and updating between the virtual and real DOM is called reconciliation. 

This approach optimizes performance by minimizing direct manipulation of the actual DOM, ensuring efficient updates and rendering of components in React applications.

3. Declarative Programming Model

Developers use declarative programming to design React applications. Declarative programming in React is a programming approach where you specify the desired state of the user interface, while creating a React component. 

Next, when the state changes, React updates the DOM based on its validation against the state. This method eliminates the need to manually manipulate the DOM, update its properties, and handle events when developing your project.

Exploring React Native

A front-end framework for creating cross-platform mobile apps is called React Native. Developers use the framework to make iOS and Android operating systems apps. The framework combines native app components to develop cross-platform app solutions.

The JavaScript library combines with the native components to improve business app development. The app code is thus represented as native, improving the user experience in general.

Features of the React Native

1. Cross-Platform Development

React Native is renowned for its cross-platform development capabilities, allowing developers to use a single codebase to build iOS and Android applications. 

This significantly reduces development time and effort, as developers can write most of the code once and deploy it across multiple platforms. The framework achieves this through native components, enabling applications to deliver a native-like experience on each platform. 

This cross-platform support benefits businesses aiming to reach a broad audience with diverse device preferences.

2. Free and Open-source

Similar to React, React Native is an open-source initiative spearheaded by Meta. The framework’s success in mobile app development is attributed to its dynamic and flourishing community of developers. 

The fact that it is free and open-source ensures that the React Native codebase is accessible to everyone, allowing for fixes and modifications to suit individual needs. 

An additional advantage of React Native is the ease of obtaining assistance or resources when facing challenges due to its expansive community support.

3. Hot Reloading

Hot Reloading is a powerful feature in React Native that accelerates the development process. It allows developers to inject new versions of the JavaScript code while preserving the application state. 

Hot Reloading feature in React Native not only enhances the development workflow by saving time but also provides a more dynamic and interactive experience for developers during the coding and testing phases. 

Use the Hot Reloading feature when developing React Native apps to expedite the testing and iteration process, resulting in a more efficient development workflow.

4. Reusable Components

With React Native, the user interface is divided into manageable, reusable components due to a component-based architecture. Sharing and reusing these components in other sections of the program or even in whole new projects is simple. 

React Native Web is an extension of React Native that enables the development of web applications using React Native components. One of the main factors contributing to React Native’s effectiveness is component reusability, which encourages a modular and maintainable codebase. 

By building a library of components that represent particular functionality, developers may produce consistent designs and behaviors across the application. This guarantees a unified and consistent user interface while expediting the development process.

Comparing Performance and Efficiency

Reactjs vs React Native

The platforms for which React.js and React Native are designed to generate differences in performance and efficiency. React.js is an incredibly efficient web development tool that uses a virtual DOM to-= create dynamic content quickly. 

Its lightweight design improves performance even more. On the other hand, React Native uses a real DOM and is intended for mobile apps, which may affect the speed of intricate pages. Cross-platform development is made possible by React Native, but developers must weigh the performance when compared to React.js. 

React Native is preferred for cross-platform mobile applications, whereas React.js is preferred for dynamic web interfaces. The decision between them is based on the particular requirements of the project. Hiring a reputable mobile app development company is the best choice who has more knowledge in both frameworks.

User Interface and Experience

React.js and React Native offer distinct approaches to crafting user interfaces (UI) and experiences (UX). React.js excels in web UI development, delivering seamless, dynamic interfaces with its virtual DOM enhancing UX by ensuring swift updates. Its declarative syntax and component-based architecture promote modular and maintainable UIs, contributing to a positive user experience.

On the other hand, React Native specializes in mobile app UI/UX. Leveraging native components, it provides a native look and feel on iOS and Android platforms. This allows for a consistent and polished user experience, which is essential for mobile applications. 

While React.js is optimal for web-based UIs, React Native’s focus on mobile platforms makes it the go-to choice for developers aiming to deliver a native-feeling UX in cross-platform mobile app development.

Leveraging Native Capabilities

React.js and React Native differ in their approach to leveraging native capabilities. React.js focuses on web development and operates within the browser, utilizing the Document Object Model. While it offers a rich ecosystem of web-specific features, it doesn’t directly tap into native device capabilities.

In contrast, React Native is tailored for mobile app development and harnesses native capabilities. By using native components, React Native allows developers to access device-specific features seamlessly. 

This ensures a more authentic and efficient integration with platform functionalities like camera access, geolocation, and push notifications. React.js is powerful for web-based applications, and React Native’s strength lies in its ability to deliver a native-like experience. The decision between these frameworks hinges on the project’s emphasis on mobile application development.


The choice between Native vs React depends on project requirements, where Native excels in native performance, while React provides efficiency with shared codebases. While React Native provides a cross-platform mobile app development solution, React.js excels at creating dynamic web interfaces and optimizes speed with a virtual DOM. The best performance and efficiency catered to your application’s requirements are ensured by carefully choosing the framework.
