React Native  

React Native is a framework released by a team at Facebook in 2015. Developers use it for building cross-platform mobile applications. React Native takes advantage of JavaScript and allows developers to share a large chunk of code between different platforms to develop Android and iOS apps easily. Thanks to this code sharing, React Native helps to reduce the development time and cost of such cross-platform applications. Companies like Bloomberg, Walmart, and Airbnb use React Native to power their mobile applications.

React Native – Pros  
  • Fast development process – since React Native is powered by JavaScript, a development team can take advantage of code built for web applications. Building and iOS apps with React Native will be 33% faster than Swift – it usually takes around 1.5 months to complete an app.

    Fewer bugs – React Native makes it easier to trace and resolve bugs before they become serious issues.
    Open source – React Native is an open-source technology surrounded by a large community that contributes to its growth.
    Hot reloading – mobile developers can visualize the code they wrote thanks to hot reloading easily. This feature makes the entire development process much more productive and faster.
    Optimal performance – since React Native uses the native components of the mobile operating system, it improves the overall performance of applications.
    Lower cost – the technology allows running the project with a smaller team and reduced the cost of cross-platform development dramatically.

React Native – Cons  
  • App store limitations – if your React Native app uses libraries that update native code dynamically, the app store will reject it. This restriction is a serious drawback for applications written in React Native.
    The need for building custom wrappers – in some cases, the development team will have to create custom wrappers to empower your application with native components, modules, and APIs. Naturally, this will take some extra time and developers skilled in native apps development.
    Security – don’t forget that React Native is an open-source framework. That’s why it carries a certain security risk. For example, if you want to develop a fintech solution that needs to meet high security standards, your development team will have to add extra security patches. Frequent updates – React Native updates its components on a regular basis. That’s why you should prepare to release your application more often.
    Cross-platform design can be complex – since Android and iOS come with different design guidelines for applications, it will be difficult to develop a high-quality custom user interface for React Native apps.
