React and React Native was introduced by Facebook to build world-class mobile and web applications with enhanced performance. They simplify the process of development and provide a comfortable experience to users. Both are famous progressive technologies that drive web and mobile applications respectively.
First, let us see the key advantages of working with React and React Native. In order to convert from a React Developer to a React Native Developer, we need to understand the similarities and differences between them.
It has Virtual DOM which is faster than the conventional full refresh model. This virtual DOM refreshes only the updated part of the DOM which makes programming faster. It is SEO friendly and improves the debugging speed and has readable code making the developer’s life easy.
It has almost all the benefits of ReactJS. It is almost similar to React but it contains Native modules and components instead of web components. It follows the principle of “ Learn Once Write Everywhere”. The main advantage is hot reloading that is the change in any business logic is live reloaded on-screen during development thus improving the performance and speed.
Both follow component-based architecture. In both systems, the main intention is to reuse UI components and reduce development time and effort.
ReactJS is a JS Library while React Native is a framework. The setup and running process of both are quite different. In React, while setting up, you need to choose a web pack and decide bundling modules that suit your project. But in React Native, you can start coding immediately after running a command line because it readily provides the package of things you require. You just need to install Xcode (in case of ios platform) or Android Studio (for Android) on your computer to run the app.
Both have different components. In React, html components like <div>,<p>,<input> are used whereas React Native uses its own native-app view components like <Text>,<View>, <TextInput>, <Image>, <ScrollView>.
Unlike React, React Native does not use CSS tags for animation. It uses built-in animated APIs to animate components of your app. You have to get yourself familiarized with React Native syntax. React uses Virtual DOM to render code while React Native uses native APIs.
If you know React which is the base abstraction of React native, you can easily learn the differences between both without learning another programming language, syntax, or workflow. The following points should be considered while changing from the React app to the React native app.
