React is the best choice for building user interfaces in web app development, while React Native is for cross-platform mobile app development. But what leads to these two separate technologies helps understand the fundamentals of both and when to choose which. We have curated this blog post explaining the key differences between React and React Native, the pros and cons of React, the pros and cons of React Native, a tabular comparison of React Native vs React JS, and more.

In the ever-evolving world of front-end development, choosing the right framework can make or break your project. Two of the most popular, and often confused, technologies are React and React Native. While they share a name and some core principles, they serve fundamentally different purposes: one powers modern web applications, and the other fuels cross-platform mobile apps.

Whether you’re trying to decide which tool to learn next or planning your next digital product, understanding the key differences (and overlaps) between React and React Native is crucial.

Let’s understand these two seemingly interchangeable technologies in detail.

What is React?

React is a JavaScript library for building user interfaces, especially for web applications.

React lets you build websites like Lego blocks. Each part of your site (like a button, a menu, or a form) is a component. You write these components in JavaScript, and they describe what the UI should look like. React then updates the webpage automatically when data changes; no need to manually touch the page’s code (DOM).

Key features of React JS:

• Component-Based: Reusable chunks of UI.
• Declarative: Describe the UI; React handles the updates.
• Virtual DOM: React creates a copy of the page in memory to make updates faster.
• One-Way Data Binding: Data moves from parent to child components, making it easier to manage.
• JSX (JavaScript XML): Lets you write HTML-like syntax inside JavaScript.
• Server-Side Rendering (SSR): Improves SEO and performance (initial load time).
• React Hooks: Add state and lifecycle features to functional components

What is React Native?

React Native is a popular open-source framework developed by Facebook (now Meta) that allows developers to build mobile applications using JavaScript and React.

Instead of writing separate code for iOS and Android, you write one codebase that works on both — and it uses real native components, so the apps feel and perform like native apps.

It came as an attempt by Facebook engineers to bring the benefits of React to mobile. At an internal hackathon, engineer Jordan Walke discovered a way to generate UI elements for iOS using JavaScript, this was the seed idea for React Native.

Key features of React Native:

• Cross-Platform Development: Write once, run on both iOS and Android with a shared codebase.
• Native Performance: Uses native UI components, not WebViews.
• Hot Reloading / Fast Refresh: Instantly see changes in your app without rebuilding it.
• Access to Native APIs: Can interact with device features like camera, GPS, file system, etc.
• Modular Architecture: Easier to separate different parts of the app and work in parallel.

What Is the Difference Between React and React Native?

At first glance, React and React Native might seem almost identical—they share a name, a component-based structure, and many of the same development patterns. But despite these similarities, they serve very different purposes and operate in distinct environments. React is focused on building modern, responsive web applications, while React Native is tailored for creating native mobile apps that run on iOS and Android.

The following table breaks down the key difference between React and React Native, including their platforms, rendering methods, styling approaches, and more.

React vs React Native: Key Similarities

Both are born from Facebook’s (now Meta) vision for efficient, component-based UI development, leveraging the same core principles of JavaScript, reusable components, and more. There is a lot that these two different technologies have in common.

Let’s explore the key similarities that tie these two technologies together, from their use of JavaScript and JSX to shared architectural patterns like component-based design and declarative UI.

Pros and Cons of React

Among the countless options, React has emerged as a favorite for web app development, backed by Facebook and used by tech giants like Netflix and Airbnb. But is React always the best choice? Like any other technology, it comes with both strengths and weaknesses.

Let’s explore the pros and cons of React to help you decide if this JavaScript library is the right fit for your next web app project.

Advantages of React

Backed by Meta (formerly Facebook) and supported by a massive developer community, React empowers developers to create dynamic single-page applications with ease. Here are the advantages that make it a go-to technology for modern web development.

• Component-Based Architecture: Promotes reusable, modular code.
• Fast Rendering with Virtual DOM: Efficient UI updates.
• Strong Community and Ecosystem: Lots of libraries, tools, and tutorials.
• JSX Syntax: Combines HTML with JavaScript for easier UI coding.
• One-Way Data Binding: Makes data flow predictable and easier to debug.
• SEO Friendly (with SSR): Can be optimized with tools like Next.js.

Disadvantages of React

Despite its strengths, ReactJS also comes with certain drawbacks like a steep learning curve, a lack of framework capabilities, and more that should be considered before adopting it. Below are the main disadvantages of using React.

• Not a Full-Fledged Framework: React only handles the view layer, requiring other technologies for a complete application.
• Boilerplate and Setup: Not being a full framework, it needs tools like Webpack, Babel, etc.
• Frequent Updates: Can break compatibility or introduce new patterns.
• Steep Learning Curve: JSX and state management (e.g., with Redux) can be confusing at first.
• Poor Documentation for Some Libraries: Especially third-party ones.
• Verbose code: Managing props, state, and logic across many components can get messy.

Pros and Cons of React Native

React Native, developed by Meta (formerly Facebook), has become one of the most popular cross-platform frameworks for building mobile apps. But while React Native promises the benefits of efficiency and code reusability during mobile app development, it isn’t without its limitations.

Let’s understand these key pros and cons of React Native.

Advantages of React Native

As a powerful framework backed by Facebook, React Native has revolutionized mobile app development by combining the efficiency of JavaScript with the performance of native platforms. Here are some advantages of React Native that have contributed to it:

• Cross-Platform Development: Build iOS and Android apps from one codebase.
• Native Performance: Uses native components, better than hybrid frameworks.
• Hot Reloading: Accelerated development and debugging.
• Over-the-air (OTA) Updates: Instantly update app logic and UI without app store approval.
• Large Community: Plenty of shared modules, libraries, and support.
• Integration with Native Code: Write platform-specific code when needed.

Disadvantages of React Native

While React Native offers powerful advantages like cross-platform development and fast iteration, it’s not without its challenges. Below are the key disadvantages of React Native you should be aware of.

• Performance Limitations: Slower than fully native apps for intensive tasks (e.g., animations, complex calculations).
• Dependency on Third-Party Libraries: Many libraries are outdated, poorly maintained, or inconsistent.
• Complex Native Module Integration: Bridging native code (Java, Swift, Objective-C) can be hard.
• Longer Debugging Cycles: A mix of JavaScript and native code makes debugging more complex.
• Limited Multithreading Support: JavaScript runs in a single thread, limiting concurrency.
