To build native, cross-platform mobile applications we can utilize a platform called react native whereas if we need a high-performance UI layer for web and mobile apps we can employ React JS which is also referred to as React or react.js.
Key differences Between React JS and React Native
How long is their development time?
To render components on mobile, React Native uses native API whereas React JS uses a virtual DOM (Document Object Model) to render browser code. DOM refers to as a logical structure of various doc formats like XHTML, HTML or XML. To name a few, Facebook, Netflix, and WhatsApp use React JS and popular mobile applications such as Instagram and Skype uses React Native. There are various benefits of using React JS over other competitive technologies. React JS applications are comparatively easy to test when compared with other competitive technologies. Whereas react native is incorporated with native components that can improve its performance. React native development has a component-based structure that helps developers to build applications in a more agile way when compared with most of the hybrid frameworks.
How is their learnability?
How responsive are them?
React Native gave more responsive and agile web application development along with better user experience to the users with a native application experience. React Native allows us to add React native UI components into the existing applications code and this eliminates the need of developers to rewrite the code. Developers usually don’t need to know the language of the native platform to build a React Native application. By integrating components of Objective-C, Java or swift with React Native code developers can optimize the efficiency of an application.
How is their performance?
Developer efficiency is increased due to the ability of React JS to give great performance along with an entirely managed rendering cycle for its components. React JS permits developers to have more chance to employ and make basic abstractions by assembling the distribution, creation, and utilization of reusable parts in a simple way. With the help of native APIs, React Native can render some code components whereas other cross-platform frameworks render code via WebView.React is also integrated with a set of native modules written in Java out-of-the-box. These modules are not cross-platform but they focus at a higher performance in computationally heavy operations like video playback or image editing.
What do they lack?
The major con of React JS is that the available documentation is in the developing stage because of the fact that the community is too young. This applies to its integration with additional tools. Other problems that developers encounter when working with React Native includes emulator issues, issues with react-navigation, package reinstallation issues, hot reloading failures and incompatibilities between various versions of React Native and community libraries. When Android or iOS update their SDKs, React Native often lags and this can be avoided if React Native’s team integrates a code library with new software. They cannot update every part of the APIs simultaneously even if they work pretty fast and this is the reason why there is a delay in the synchronization between React Native and new SDKs.
