Take a look at our guide to gain a thorough grasp of React Native’s workings before implementing it into your applications. You can use this understanding to determine if it fits with your requirements and goals.

What Is React Native?

React Native is an open-source, popular JavaScript framework crafted to develop apps across various platforms like iOS, Android, and even web applications, all while using the same code. Built on the foundation of React, it brings that same power and versatility to the world of mobile app creation.

Both ReactJS (for the web) and React Native hail from Facebook. React Native emerged from a Facebook Hackathon, aiming to tackle a major headache for the company: managing two separate code bases for their app. The issue? Duplicating work and often solving the same problems in different ways. React Native steps in as a direct solution to these challenges.

Using JavaScript, React Native compiles the app’s user interface while employing native OS views. When dealing with more intricate features, it allows developers to implement code in OS-native languages like Swift and Objective-C for iOS and Java and Kotlin for Android.

Why Use React Native?

React Native is becoming more and more well-liked in the field of development. Here are the top reasons to select React Native app development companies to build an app in 2024.

Cross-Platform Compatibility

One of the standout perks of React Native development is its ability to create apps for both Android and iOS at once, using the same codebase with minor adjustments tailored to each platform.


With React Native, you can sidestep the need to learn specific languages for individual platforms. Instead, it relies solely on JavaScript, widely acknowledged as one of the most popular programming languages today for mobile app development.

Performance Boost

React Native streamlines app development by utilizing similar code across platforms, leading to quicker turnaround times. Its hot reloading feature ensures that even small changes made to the app become instantly visible to developers, enhancing the development process.

Robust Developer Community

A thriving community ensures the timely resolution of queries, providing ample support for the React Native framework. The active community consistently updates React Native with new features and bug fixes, ensuring its growth and reliability.

Promising Career Opportunities

Due to its rising popularity and benefits, React Native for cross-platform development has led to a surge in demand for React Native developers, promising bright career prospects in the field.

What Is Cross-Platform Development?

Cross-platform development involves crafting software that works seamlessly across various platforms or devices using a single codebase. Rather than creating separate versions, developers use one codebase to run on multiple platforms, like making mobile apps for Android and iOS simultaneously. This approach saves time and resources, boosting overall efficiency.

It enables developers to work on platforms they might not typically use, employing their preferred frameworks like JavaScript. From a business standpoint, cross-platform development speeds up the time-to-market and reduces both development and maintenance costs. These advantages make it an immensely sought-after approach, catering to both business and technical needs.

Comparing React vs. React Native

React is a toolkit primarily used for crafting User Interfaces (UIs) for websites. Its strength lies in creating reusable components that boost the functionality and appearance of web pages. A React JS developer focuses on creating a seamless user experience across various platforms, tapping into the versatility offered by React.

Initially developed by Facebook in 2011 to address website performance issues caused by frequent updates, React found success and was adopted by Instagram after Facebook’s acquisition in 2012.

React Native, created by the same team at Facebook, is React’s counterpart tailored for mobile app development. It harnesses React’s capabilities to build applications with performance close to native apps, all powered by JavaScript.

To simplify, React focuses on website development, while React Native, which is not reliant on HTML, specializes in creating sophisticated mobile applications. Both are connected but fulfill different roles in software development. Also, explore the comparison between Flutter vs. React Native in this guide.

How Do React Native Work?

React Native functions as a framework enabling app development through JavaScript threads that interpret code. It establishes a connection, known as the native bridge, between the app and the intended platform. This bridge utilizes a library to transmit the component hierarchy to the mobile device’s view.

When a user interacts with the app, such as pressing a button, this action is converted into an event that JavaScript manages. The native bridge facilitates the translation of these native events into a format compatible with React components. By exchanging messages between native platforms and JavaScript code, React Native ensures that these events are understandable and actionable within the React component environment.

Benefits of React Native

React Native stands out as one of the most sought-after front-end frameworks. If you’re still weighing the possibilities for your project, let’s have a look at some of its key advantages:

1. Code Reusability

React Native excels in enabling efficient development across multiple platforms simultaneously. Leveraging the same code base for different platforms offers several benefits, including expedited app development and quicker time-to-market, simplified and cost-effective maintenance (managing a single code base), and smoother onboarding for new developers joining the project. Furthermore, the same React Native code can be utilized for both web and mobile applications if they’re built using React Native.

2. Cost Efficiency

React Native development provides greater cost efficiency by allowing developers to use identical code for iOS and Android applications. This removes the need to hire separate teams for each platform, reducing the overall cost of app development. Building apps in React Native tends to be more cost-effective compared to languages that lack cross-platform development capabilities.

3. Simplified UI

React Native uses React JavaScript to craft the app’s interface, enhancing responsiveness and reducing load times, resulting in an improved user experience. Its reactive UI and component-based approach make it ideal for developing apps with both straightforward and intricate designs.

4. Hot Reloading

The Hot Reloading feature empowers developers to view real-time changes in their code without the need for manual refreshes. This seemingly small feature significantly enhances the development process by providing immediate feedback on code alterations, boosting productivity. Moreover, it allows reloading specific parts of the code, saving time that would otherwise be spent on complete compilations.

5. Future Proofing

Since its inception, React Native has experienced continuous growth without showing any signs of slowing down. This implies that it’s unlikely to become obsolete in the near future. Opting for React Native ensures you won’t have to worry about switching frameworks anytime soon.

Drawbacks of React Native

Every technology has its downsides, and React Native is no exception. Here are some drawbacks to consider:

1. Incomplete or Absent Custom Modules

Despite its maturity, React Native lacks specific custom modules that either require improvement or are absent. This can necessitate the maintenance of three separate codebases (for React Native, iOS, and Android) instead of consolidating efforts into a single one.

2. Compatibility and Debugging Challenges

Despite being used by leading tech companies, React Native is still in a phase where it might encounter package compatibility issues. If your development team isn’t well-versed in this framework, troubleshooting these problems could consume considerable time and effort.
