What is a React Developer?

This snippet will look differently in the current state of the git repo as I added this after initially writing the article – but you can check the correct code on the latest tree, too. My initial idea was to make the grids size the square root of the points – so when you reach 4 points it is 2, at 9 points it is 3, at 16 points it is 4, and so on. But I needed a minimum size for the grid (2) because before reaching that, there would be either zero or one tile. I also wanted a hard cap on the maximum size of the grid (it’s 5 in the example, but it could be any number you’d like). Call the this.generateNewRound() at the top of the componentWillMount() to make sure that the game initializes a round when the player opens the screen. If you reload the app and try to swipe back from the Game screen, you’ll notice that you can’t, and that’s the behavior we wanted to achieve, so let’s move on.

As an example, let’s consider a view/page that contains a cart summary along with a promotion calculation under certain conditions. The code responsible for calculating the total cost and the discount can be transferred to a new library (cart.js), while individual platforms are only responsible for displaying the cart view. One option to achieve this is by using React Native Web (it’s used in the mobile version of Twitter, just to give you an example). React Native Web is a library that adds support for a new platform – web. For example, the code in React Native needs to know when the user has pressed a button, typed text into a text field, or switched to another view to react to it accordingly. The task of the built-in mechanism in React Native Bridge is to ensure communication understandable for both environments.

What makes React Native unique?

They planned, however, to bring Shine to Android users if their iOS app gained popularity. After shifting to React Native, the performance of both iOS and Android apps improved immensely – to a nearly native-level. Ninety-five percent of the codebase is https://wizardsdev.com/en/vacancy/react-native-developer/ shared for Android and iOS; furthermore, there’s a single team that manages and develops both apps. The American grocer has been known for making bold technological decisions – and one of them was rewriting its mobile apps entirely into React Native.

React Native is a great choice for startups and for projects that don’t require complicated interfaces, logic, and access to native mobile features. By using React Native, you can reach a large audience at once – as one app can be used by both Android and iOS platforms. Before React.js was introduced, developers back then were stuck building UIs using raw JavaScript or with jQuery (a React predecessor that focused less on UI). This meant that the development process took longer with more room for errors and bugs.

Step 2: Start your application​

As it showed, React Native bridges JavaScript with native mobile code. This means that if you put a developer who doesn’t have knowledge of native mobile development in charge, they will have a hard time incorporating native code into the RN codebase. As a result, you’ll need some assistance from Android or iOS native mobile developers, to guide them through the process. While they initially intended to develop two separate native apps (and start off with iOS), they found it hard to recruit a team of iOS engineers. They were also worried that developing two separate apps would mean they wouldn’t be able to synchronize releases for iOS and Android. It is a common myth that cross-platform apps perform worse than their native counterparts.

  • This list may include some specific skills related to the position or requirements of the company.
  • React Native uses the mechanisms of ReactJS in line with the “Learn once, write everywhere” principle, and the main difference between the siblings is the type of application under construction.
  • Nothing stands in the way of making the appearance of individual components consistent so that they look the same, regardless of the platform.
  • With Sourcebae, you can hire our AI-Vetted skilled, experienced, and expert tech talent on a contract for Remote and Onsite locations.
  • Most of the consumer-facing apps do not rely on complex animations and UIs which, again, makes React Native a great and reliable solution for the endeavour.
  • It will display the speaker icon, but to push it to the right side of the screen, you can either play with adding margins, or adding a  before the button.

The performance is near native, and the number of case studies from companies (big and small) confirms that it seems to check all the boxes for both users and businesses themselves. Facebook apps for iOS and Android are not the only ones relying on React Native. Instagram started exploring React Native in 2016, and in their blog post, they also expressed it allowed their product teams to ship features faster on both platforms, iOS and Android. They also shared the percentage of code shared between the apps which  was directed at improving developer velocity. If you’re building an app that involves many events, a lot of data, etc.


Upon completion of this course, you’ll have a Native project to add to your professional portfolio and a certificate from Meta for your resume. Discover top IoT app development companies that turn innovative ideas into reality. Explore experts in creating cutting-edge Internet of Things applications to redefine connectivity and efficiency. A native app is an application developed specifically for that platform, for example an app installed from the Play Store, or an app from App store.

Let’s move to the part that is more useful for aspiring React Native developers – React Native Interview questions. This list may include some specific skills related to the position or requirements of the company. But, overall this sums up nearly all skills that are required for this role. If you’re new to the world of web and mobile development, you might be wondering the same thing. Simply put, UI is a term that describes any element that allows users to interact and communicate with the information saved in a device (laptop, tablet, smartphone, etc.). The user interface is the primary point of contact between humans and modern computers.

What does it mean for your app?

We’ve discussed the products built using React Native, so let’s move onto the advantages of React Native development and why you should choose it as a solution to build your mobile app. In 2017, Skype announced that it was building a completely new app based on React Native. This brought a lot of excitement from its users, as the older version suffered from a few issues. Cross-platform development is the practice of building software that is compatible with more than one type of hardware platform. A cross-platform application can run on Microsoft Windows, Linux, and macOS, or just two of them. A good example of a cross-platform application is a web browser or Adobe Flash that performs the same, irrespective of the computer or mobile device you run it on.

Additionally, React uses some HTML and CSS, whereas React Native allows the use of native mobile user interface elements. When React Native was first released, it had an enormous impact on the mobile development community. A Web Developer could now build a complete mobile app using one codebase. Rather than install and manage a specific version of the CLI globally, we recommend you access the current version at runtime using npx, which ships with Node.js. With npx react-native , the current stable version of the CLI will be downloaded and executed at the time the command is run.

After recognizing how it made mobile app development so much easier, Mobile Developers and businesses immediately started using React Native. It also lowered the barrier to entry, as web development teams could now build mobile apps with only a little extra training. With React Native, you can use the same technologies and programming languages used for web development.

React Native Developer  meaning

However, you can also seek employment as a freelance developer or on an engineering team. React Native developers are software developers who specialize in using the React Native framework to build mobile apps. A clear and comprehensive React Native developer job description helps you attract highly skilled engineers to your organization. From making visualizations that can render huge quantities of data to the development of web applications, a skilled React Native developer can handle them all. Companies that wish to have developers who can help them in creating user-facing software solutions, adding new features, and fixing problems must hire the best React Native developer.
