ReactJS specializes in its ability to provide a great performance and a fully managed render loop for its components. By simply customizing the distribution, creation, and use of reusable components, it allows developers to have more options to use and create basic abstractions. This turns out to be useful for low-level components such as buttons, as well as higher-level items such as dropdowns. React Native provides the same profits, but with a different approach. React Native blocks are reusable components that are compiled directly into the native environment. The components you’ll be using in Android or iOS have counterparts in React, so you’ll get the same look and feel. This structure provides faster application development. This application will have the view, speed and functionality of its own mobile application and that makes React Native different from other frameworks.
ReactJS integrates technologies, while React Native code can be combined with any existing application.
React uses HTML and JS, following the rule that they go hand in hand all the time. This idea has been extended with CSS, which eliminates many of the worldwide scope and variable / scoped isolation issues. On the other hand, React Native provides opportunities for companies that want to improve an existing application but don’t want to change the whole thing. You can add React Native components to your existing app code. Or if your current mashup was made with Ionic and Cordova, use that Cordova based code with a plugin.
