So, let’s consider both of them in detail to understand what is the difference between React.js and React Native.
What is React.js?

Why so? Let’s explore the pros of React.js.
Benefits of using React.js
It provides the document object model (DOM), a viewing agreement that works with data input and output. The secret of quick work of DOM is that it updates only parts of pages while other models refresh them fully. Such a way of updating increases productivity and upgrades programming processes. It is interesting that Facebook developers didn’t know in advance that this kind of page updating will be a solution.
Working with React.js, you can reuse the code components, which will save your time.
Rendering pages from the server to the browser is good for the SEO of your web application.
It increases debugging speed.
It is easily readable, even if you see this framework for the first time.
Drawbacks of using React.js
The appearance of new tools is always connected with the loss of documentation. Developers don’t have time to write proper documentation about React.js and write it only for current projects.
You should do some additional testings to be sure that your web application is indexed by Google (there were some unpleasant cases soon after React.js appearance). SEO specialists recommend developers to run React.js application with the help of a dedicated Google tool, Fetch. It can show how search engines take the application.
What is React Native?

React Native is also gaining in popularity for a couple of reasons.
Benefits of using React Native
React Native provides its own API for code visualization and increasing productivity, while other cross-platform frameworks work through WebView.
React Native has all advantages of React.js for better UI.
React Native allows developers to reuse common logic levels, so you shouldn’t develop the same application for iOS and Android.
React Native is appropriate for developing applications with the agile approach to the web style.
You don’t need to rebuild or rewrite your old application. You can just add components of React Native to the code of an already existing application.
React Native provides high speed and agile development applications, effective data processing, and better user experience for your customers.
Drawbacks of using React Native
React Native, like React.js, also has poor documentation. Developers make documentation only for their current projects, so there are gaps in instructions, especially about integration with different tools.
If your application is complicated and suggests heavy operations and injection of native modules, you require the help of objective-C and Java engineers.
React Native provides an insufficient number of features, for example, several out-of-the-box solutions for iOS and Android that can be no longer supported after the next update.
The full synchronization process between React Native and iOS or Android SDK can take a long time. Developers shouldn’t update all parts of the API when they integrate the code library with new software.
React Native is a young tool that has errors and some problems with compatibility. For example, it can be required to frequently reinstall packages, solving problems with the emulator, react-navigation, or reloading failures.
