React Native vs React JS: What Are the Main Differences?
All the differences between ReactJS and React Native derive from one major distinctness – the field of appliance for both tools.
React Native is a comprehensive framework meant for building native, cross-platform mobile apps for Android and iOS.
However, it’s important to keep in mind that React Native derived from ReactJS. Which means, they share the same core, same basic syntax and same approach towards development process.
Basically, it is still React code, but the framework possibilities offer additional functionality to run your app on mobile platforms. And, one more great bonus – if you know React, you practically know React Native. Which is an astonishingly useful feature in React development, and any kind of application development at all?
In a nutshell, ReactJS is responsible for building a hierarchy (rendering) of UI components while working with both frontend and server-side. Its distinguishable features are:
Easy to learn. It is quite readable even for those who aren’t familiar with React at all. Unlike to other frameworks which require you from your learning of a huge list of concepts which are only useful within the framework. Even easier to work with. You can reuse code components in React JS. Needless to say, that saves you a lot of time.
React’s virtual DOM refreshes only parts of the page. This is the central and most beloved feature in ReactJS. It dramatically increases the performance of application and development speed. Thanks to its Web Inspector, ReactJS also improves the debugging speed drastically. Which, of course, improves development speed even further, by making your life easier. The way how ReactJS renders your pages completely, from the server to the browser greatly improves the SEO of your web application.
As a great additional bonus, you get all the advancements in Java language and its ecosystem. As we said, if you’re familiar with ReactJS, it won’t be a problem for you to pick up React Native. If you’re not – it is better to start with ReactJS. It is way easier than React Native, as it has much fewer components to learn. Building one or two medium sized apps with ReactJS will help you a lot in your progress with React Native. Speaking of which…
React Native lets you build part of your app in React Native, and part – using the native code directly. Unlike routing to different web pages in web development, you have to navigate between different scenes of your app in React Native. For that purpose, you’ll have to use Navigator (or Navigator IOS for iOS) component provided by React Native.
So yes, these two are fundamentally same. All that differs them is what are they used for. React Native derived from ReactJS as a specific tool for building mobile applications. As a consequence, it had to be adapted. The absence of HTML and CSS are the necessary sacrifice. However, your experience in writing a web application on ReactJS is more than valid. And once you become proficient with both – web development and mobile app development are open to you.
