These two technologies are beneficial for creating scalable online and mobile solutions. Facebook created both of these to make it easier to create online and mobile user experiences with JavaScript.

Although there are some similarities between the two, it is critical that you thoroughly grasp them and what they include so that you can make a well-informed choice when choosing one of the two for your project.

In terms of popularity, React is utilized and liked by more than 41% of developers worldwide. On the contrary, React Native is preferred by 32% of software developers globally.

Both options are popular, making a choice between them more difficult than expected. Let’s scroll to find out about these two amazing platforms, features, pros & cons, major differences, and even similarities.   

What is React?

ReactJS is an open-source front-end programming library created and launched by Facebook in 2011. It is widely used to create feature-rich, responsive, fast, and user-friendly mobile and online apps. Additionally, it allows them to automate the design process. It is one of the most popular libraries for creating user interfaces (UI) for web and mobile apps, and it has grown in popularity since then.

ReactJS developers can simply integrate plugins or libraries into their existing code. Additionally, it makes it possible for them to create straightforward, quick, and scalable web apps. The introduction of React in front-end programming brings back much-needed server-side logic.

Because the library is based on JavaScript, developers have access to a vibrant community of participants who have developed a massive environment of tools to make an engineer’s task simpler. It includes React Developer Tools (inspection of component hierarchies in the vDOM) and React Sight (visualization of component hierarchy tree).

Features of React

• Virtual DOM: ReactJS utilizes a virtual DOM to represent the UI in memory. This virtual representation allows React to efficiently update the actual DOM by only re-rendering components that have changed, resulting in improved performance.
• Component-Based Architecture: React promotes a modular approach to building user interfaces by breaking them down into reusable components. Each component encapsulates its logic and UI, making the codebase more organized, maintainable, and scalable.
• JSX: JSX is a syntax extension for JavaScript that allows developers to write HTML-like code within JavaScript. JSX enhances code readability and enables developers to express UI components in a more intuitive and declarative manner.
• Declarative Syntax: React uses a declarative programming paradigm, allowing developers to describe the desired UI state and let React handle the underlying updates. This simplifies the process of building complex UIs and reduces the likelihood of bugs.
• Event Handling: React provides a consistent and efficient way to handle user interactions and events within components. Event handlers can be defined inline within JSX or bound-to-class methods, allowing developers to create interactive UIs with ease.
• State Management: React allows components to manage their state using the useState hook (in functional components) or the setState method (in class components). It enables components to maintain their internal state and trigger re-renders when the state changes.

Pros 

• Improved Performance: React’s efficient use of the virtual DOM leads to faster rendering and a smoother user experience by updating only the necessary parts of the interface.
• Modular Development: React’s component-based architecture fosters a modular approach to development, making it easier to build, maintain, and scale applications by reusing components across the codebase.
• Simplified Development: React’s declarative syntax allows React developers to focus on describing the desired UI state, resulting in cleaner and more maintainable code.
• Enhanced Readability: JSX enhances code readability by allowing developers to write HTML-like code within JavaScript, making it easier to understand and collaborate on React projects.
• Robust Ecosystem: React’s vast ecosystem of libraries, tools, and community support provides developers with resources to address common challenges and accelerate development, leading to faster time-to-market for projects.
• Cross-Platform Compatibility: With frameworks like React Native, developers can use React to build not only web applications but also mobile applications, allowing for code reuse and consistent user experiences across different platforms. 

Cons

• Complexity: React’s ecosystem and concepts like JSX, virtual DOM, and component lifecycle methods may have a steep learning curve for beginners. 
• JSX: While JSX can improve code readability, some developers may find it cumbersome to mix HTML with JavaScript, especially if they prefer a clear separation of concerns. 
• Tooling Overhead: Setting up a React project with tools like Webpack, Babel, and ESLint may require additional configuration and costs, especially for smaller projects.
• Limited SEO: React applications rendered on the client side may face challenges with search engine optimization (SEO) compared to server-rendered applications. 
• Performance Overhead: While React’s virtual DOM offers performance benefits in many cases, it may introduce overhead for simple applications or scenarios where direct DOM manipulation would be more efficient.

What is React Native?

React is an open-source JavaScript toolkit that is frequently used to create applications that look and feel native on platforms such as iOS, Android, and Universal Windows Platform (UWP). 

Mark Zuckerberg vowed in 2012 that Facebook would provide a better mobile experience, which inspired the development of React Native. This platform was created in response to the increasing demand for high-calibre cross-platform programming, following React.

Mobile app developers can save a ton of time using React Native because their team won’t have to split its efforts between developing apps for iOS, Android, Windows, and other platforms. Most of the JavaScript code might be reused and improved with native modules or code. 

React Native is one of the most widely utilized technologies, according to the Stack Overflow poll 2020, with 58% of respondents stating they had developed mobile apps using React Native.

Features of React Native 

• Cross-Platform Development: React Native enables developers to build mobile applications for multiple platforms using a single codebase, including iOS and Android. This cross-platform compatibility reduces development time and effort compared to building separate native apps for each platform.
• Reusable code: React Native’s greatest accomplishment is that it eliminates the need for programmers to write separate code for the iOS and Android platforms. They can reuse the code as & when required and help streamline development efforts and reduce maintenance overhead
• Responsive UI: React Native can give consumers a native-like experience because it uses native UI to create responsible mobile apps. If you have a limited budget yet require a cost-effective and high-quality solution that can run on multiple platforms, React Native is your best option.
• Hot and Live Reloading: If you need to change the business logic, you may utilize React Native’s Hot and Live reloading to change the user interface without losing any code from your project.
• Declarative UI: The concept behind this feature is rather straightforward: it renders content by returning some JSX. Mobile UI is built on a declarative programming approach, which allows programmers to focus on what needs to be implemented rather than how to achieve it.
• Offline Support: React Native supports offline capabilities through libraries like AsyncStorage and NetInfo, allowing developers to build apps that can function without an internet connection. This is crucial for applications that require data persistence or work in areas with limited connectivity.

Pros

• Reduced costs: Because there is only one code base for all platforms, React Native may be used to create Android and iOS-compatible apps. As a result, the business will save money on development, upkeep, and administrative expenses. React Native’s complete license-free nature accounts for the additional cost savings.
• Access to Native APIs: React Native provides access to platform-specific native APIs and functionalities, allowing developers to integrate device features such as cameras, GPS, sensors, and push notifications into their apps. This enables developers to create rich and interactive mobile experiences.

• Learning Curve: Developers familiar with web development may need time to learn mobile development concepts and the React Native framework, particularly if they are not accustomed to writing mobile-specific code or working with native APIs.
• Debugging Challenges: Debugging React Native apps can be more challenging compared to web development or native mobile app development, because the issues related to bridging JavaScript with native components may require specialized debugging techniques and tools.
• Dependency on React Native Updates: React Native’s frequent updates and changes may introduce compatibility issues with existing codebases or third-party libraries. Developers need to stay updated with the latest releases and be prepared to adapt their apps accordingly.

React Native vs React: How Do They Work?

ReactJS & React Native are two popular platforms, and as we stated ut vary significantly and so does its working process. Let’s find out how both of these technologies work. 

The Working of ReactJS

React works by deconstructing the user interface (UI) into reusable parts, like forms or buttons. It reduces performance bottlenecks by efficiently updating only the areas of a web page that change through the use of a Virtual DOM.

React takes a declarative approach, in which developers express how the UI should look based on the data, and React handles updates immediately when the information updates. This makes creating interactive web apps easier and more manageable by incorporating state management for dynamic content and handling events for user interactions.

The Working of React Native

React Native is a mobile app development platform that lets programmers write code in either JavaScript or TypeScript. It ensures a native appearance and feel on iOS and Android by using native components for the user interface.

When necessary, a bridge that joins native modules and JavaScript logic allows access to platform-specific functionality.

Developers can reuse a large percentage of their software across platforms, making it an effective tool for cross-platform mobile app development.
