What makes React Native so special and why web developers are starting to learn React Native?
React Native is the future of modern app development
More and more web developers are getting into the app-building ecosystem. According to stateofjs.com, 78% of developers are interested in learning about the new kid on the block: React Native. In addition, React Native has a high 92% interest rating—and for a very good reason.
So what makes React Native so special? Here is a list of the top five things that will primarily interest web developers.
1. You can build native applications.
As you probably guessed from the name itself, React Native lets you build native applications. Cordova and other types of framework, like Sencha Touch or Ionic, are hybrid solutions, and with them, you will never achieve the look and feel of a native app.
It’s the little things that matter: fluent or accelerated scrolling, transitions between screens, totally custom animations, custom navigation, and so on. If you ever worked with React on the web, you’re in for a treat because you’ll feel right at home.
The main problem with hybrid technology previously was that the embedded browser just didn’t work well enough. It wasn’t optimized, and it provided poor performance.
From a technology standpoint, the biggest competitor for RN is Xamarin, which lets you develop apps for lots of platforms: Mac, Windows, iOS, Android, Windows Phone, you name it. Native Script also works in the same way.
I recommend this talk as an intro to React Native so you can learn how it works.

2. It’s easy to learn.
That’s always a good thing, right? It’s also one of React Native’s greatest strengths. It’s readable like a children’s book, so you can just glance at it. With other frameworks, you are usually forced to learn a long list of concepts.
Over time, Facebook significantly improved their official React Native documentation. Recently, they added the basics section, which is a really neat, clever way to learn RN because it explains everything you need to know in a straightforward crash course.
It uses JSX, which is basically like HTML. Styles are very similar to CSS, but they are written within components and not in a separate single file. There are pros and cons to that approach, and many articles have been written about it. So really, everything you need to know is React.
React is easy. Imagine a div component named “View” and another text component simply named “Text.” This is essentially the connection between React Native and React.js.
Styling is very similar to CSS, except it’s included with the component itself and not in a separate file.
That’s really easy, isn’t it?
For starters, you should learn about the React lifecycle, states, and props. Trust me, it’s all downhill from there.
3. It offers a familiar environment.
Are you used to transpiling the code with Webpack, Grunt, or Gulp? React Native does it for you. ES6 and some of the cool ES7 features, like Object Spread, are available right out of the box because RN uses the Babel transpiler.
Another thing that will make things, if not familiar, then definitely easier to work with is Nuclide, an integrated development environment (IDE) that Facebook is building to give developers a first-class developing environment for React Native.
It’s important to note that the flow you’re used to still works. Just like working on the web, updating index.html updates the whole page. Hot Reloading enables you to easily refresh the code and see changes in your app instantly. Just like on the web. Even better, press CMD+D in the simulator and you’ll get number of options to choose from.
4. It has an active community.
Since this is all pretty new, uncharted territory, a lot of developers are doing their best to build something useful to others and unveil the true potential of React Native.
Facebook groups will give you a great overview and keep you posted about relevant news, so, there is little chance that you’ll miss something important if you’re following those groups.
The biggest, most active groups is React Native Community, which offers daily posts about toolkits, components, new apps, and answers to questions about React Native, from basic questions to serious developer problems. This makes it a good place to gather information and learn something too.
If you’re more of a reader, Medium is also booming about React Native. There are a few publications, but the best way to dig in is to follow the React Native tag.
When you have a problem, visit Stack Overflow, where you’ll find a ton of advice and solutions to problems. In terms of programming in general, programmers are more or less used to finding stuff that someone has found a solution to. When you have issues with React Native, you can find and instantly reuse code someone else has written.
There are also a lot of events happening focusing on React Native. The most popular events are organized through Meetups. These events take place all over the world every few weeks.
The biggest one is definitely React Native San Francisco, but at the time of this writing, the most recent one was in New York. It hosted more than 100 active React Native developers. There are also lots of conferences like React Europe, which had 1000 participants this year!
Overall, React Native has over 40K stars on GitHub and over 9K forks. The Facebook groups dedicated to it have 7K members, and lots of new articles are written about it every day.
5. It offers a cross-platform framework for the future.
The word “cross-platform” used to leave a bad taste in my mouth. But trust me, this is different. With React Native, you aren’t building true native mobile apps; you’re building apps for all platforms.
And when I say all platforms, I don’t mean only iOS and Android; I mean smart TVs, Xbox consoles, Windows devices, all kinds of smart watches, cars, VR headsets, and heck, even refrigerators.
That’s not to mention that smartphones themselves have become powerful machines. The times have really changed since the whole “mobile first” paradigm, and some developers are even talking about “native first.”
The technology is still pretty new, but there are some excellent React Native apps right now. Still not convinced it’s the framework of the future? Watch this presentation and everything will fall into place.
Give it a go! It’s time to become a mobile developer.
As we’ve explained, this framework really has potential, and not just for web devs. The whole development logic uses modern principles; the workflow is efficient, easy, and quick to learn; more and more platforms are using it; and all of that is just the start.
That’s where you come in: a new React Native developer, resolving problems and bringing new ideas to this fast-rising framework of the future.
