Pros & Cons of React Native App Development



React Native is an open-source framework that permits you to create a mobile app only using JavaScript. It was introduced by Jordan Walke, a Facebook software engineer, as a new technology for simpler development and a better user experience. The main distinctive of this framework is that React Native apps functions a bit like native apps. They don’t differ from apps built on Java, Objective-C or Swift and that they use an equivalent UI building blocks as native iOS or Android apps. But with React Native, building a mobile app is far faster and fewer expensive.

PROS 

Strong performance for mobile environments

The React Native architecture is extremely well tuned to mobile devices. It makes use of the GPU (Graphics Processing Unit), while native platforms make use of ‘CPU (Central Processing Unit) intensive’. Compared to hybrid technologies – which was the sole option for cross-platform within the past – React Native is superfast.

Maximum code reuse & cost saving

By using React Native, you'll use an equivalent code for deployment on iOS also as on Android. This means an enormous saving in development time and price. Theoretically, the event effort might be cut by half. In practice, the value saving is going to touch lower but still quite interesting enough to form the investment worth your while. According to recent calculations, about 90% of the code are often reused between Android and iOS, but it might be taking to calculate some overtime for practical modifications as well.

Large Community of Developers

As React Native is an open-source JS platform where every developer is liberal and easily accessible to any. So, you can take full advantage of the community-driven technology.
This means that if any developer gets stuck somewhere while developing an app, he is free to take the help of the community members who would guide him in this regard.
Keep in mind that React Native has been developed by Facebook, the King of Social Media. In this way, you would likewise get broadened support from the online.

Support for Third-Party Plugins

The React Native also extends its support for the third-party plugins providing a pair of options that include native modules and JavaScript modules. This is because it does not have some components in the main framework.

For instance, if you're implementing any Map in your app, React Native allows you to do so by connecting the plugin with a native or third-party module.

Live reloading

Live reloading reads and compiles a file in which changes were made by a developer and then provides a new file to the simulator, which automatically reloads the app from the starting point.

CONS

React Native could be not suitable for all applications. If the application should have a large number of complex animations or massive computing by your device resources, then the typical native app will work better and faster. Why? Because such things in native code could be in several threads, and it is doubtfully in JS. 

High cost of development

Native isn't the answer for the faint of wallet. Money is the #1 reason to think about alternatives. Developing 2 separate native apps for iOS and Android requires establishing two specialized teams of developers.

Time consuming

iOS and Android apps have at the core 2 completely different source codes, which suggests that not only initial mobile app development is more complex, but also the following maintenance, updates and servicing of the software requires considerably more resources. That meant that it's very time-consuming to develop two top quality, tested product. Two separate technologies namely android and iOS will influence all the stages of the app’s lifecycle.

Actually, React Native doesn't have so many cons. Of course, app performance isn't up to the standards of these created with platform-specific logic. There's also the fact that it's still a new development framework and that the number of ready-made components (one of the biggest React Native advantages) is quite small.
