This makes it the best choice for native app projects requiring an app for both the markets. React JS is a front-end library based on JavaScript for creating interactive UI web apps. React Native is a cross-platform framework for developing mobile apps for Android, iOS, and Windows Mobile. Although both technologies use reusable code, they still have some minor differences. For example, in React JS, components are named in the HTML format (p, h2, etc.), while in React Native they are View, Text, etc.

Our Client, the US farm-tech startup, came to Belitsoft to create a mobile and web app that resolves a rural labor shortage challenge across the USA. Belitsoft has helped the training company to deliver highly effective, personalized online learning through a custom LXP to their first corporate client. Even the library’s official website is called “reactjs.com,” although the headline says “React.” Thus, there is no difference. 3 Agile ReactJS Development — the work gets split into “sprints” (1-4 weeks depending on the project). At the end of each sprint there is a demo session where you can see the working functionality we’ve developed.

In this article, we saw that React Native is similar to React, which itself is a JavaScript library to make interfaces. Consequently, you need to ace web technologies like JavaScript, JSX and even CSS-like stylesheet syntax for component customization. Despite having a few complexities, the React Native Framework has breezed through every one of the tests and obstacles to end up as the first choice for many developers. The Cordova or Ionic produced graphical interface is shown through a Web View, which expels its productivity and quality and also the client experience.

Many people are currently assessing React Native as a platform to develop their next mobile app on. Switching your software development platform involves a high setup cost and will profoundly impact your daily programming workflow. It is also one of the costliest decisions to reverse after anything substantial has been built. Because React Native replicates front end design components of React JS, it means your web developers can make mobile apps with a little training if required.

Testing React JS apps is easy due to the technology’s peculiarities. Our testers can easily track the performance of your UI with click events to ensure the layout is simple to use, effective, and flawless.

If it’s a problem that the compiler can solve, you let the compiler solve it – and tackle interesting problems instead. The fact that millions of drivers productively drive cars without wearing a seatbelt isn’t a good argument for cars with no seat belt. Similarly, the fact that millions of JavaScript developers productively use an inherently unsafe language isn’t a good argument for the use of unsafe languages. In various GitHub issues and forums posts, developers have claimed that their legal departments have advised them not to use React or React Native precisely because of this clause. Matters remain deplorably ambiguous for developers who don’t have a legal department at hand. Any changes in your JavaScript code can be instantly pushed to your users while the app is in production.

React primitives render to native platform UI, meaning your app uses the same native platform APIs other apps do.

Performance Optimization

React Native resembles React JS, however, it utilizes native components rather than web component as crucial building blocks. You have to see a portion of the fundamental React ideas, as JSX, components, state, and props to grasp the essential structure of a React Native application. Coming to React Native, the final User Interface does not simply render a web component inside a WebView. The User Interface is rendered using actual native views and fundamental building blocks that are indistinguishable from the apps built using Swift or Java.

The final list topic I’d like to touch upon is scrolling to the top of the list with the press of a button. In my app, I currently have these buttons in the headers, but another common location for them is in the bottom tab buttons. The second problem I ran into with infinite scrolling was what I can only assume is a FlatList bug. Namely, that every single time I scrolled down passed the threshold, my handleLoadMore() function passed to the onEndReached prop would be called repeatedly, often more than 10 times in a row.
