As of 2021, JavaScript and HTML/CSS were the most commonly used programming languages among software developers around the world with nearly 65 percent of respondents stating that they used JavaScript and over 56 percent using HTML/CSS according to one Statista report.

Cross-platform app development has changed the way how enterprises and small businesses consider building an online presence. It has made mobile app development faster, easier, and cheaper as it allows building one codebase that runs across different platforms and devices. While there are many software and frameworks for developing cross-platform apps, JavaScript still remains the king of cross-platform development.

The reasons are clear – a huge JavaScript ecosystem, its foray into front-end development along with usage in backend development, and ubiquity of JavaScript. This has resulted in the increased popularity of JavaScript-based frameworks and libraries such as React, Node.js, Vue.js, AngularJS, and so on.

We are here to talk about one of the popular roles based on React Native app developmentReact Native Developer. Here, in this article, we will be talking about React Native developers, react native developer skills, roles & responsibilities, react-native interview questions, react native developer salary, and more.

Why Hire React Native Developer?

Hiring react native developer not only saves your time and cost but also results in improved performance, speed, and experience.

Here are some benefits of hiring React Native Developer to build mobile applications:

Cost-Efficiency:

This is obvious as using React Native, you can build a single app for different platforms (Android and iOS). By using the same codebase for multiple platforms results in cost-saving and time-saving. Cross-platform development saves time as it offers maximum code reusability except for native UI components building.

Great Performance:

While, practically no other option can beat native app performance but when you have requirements for cross-platform, React Native is a winner. The architecture of react native is very well-formed and tuned to mobile devices. It uses GPU (Graphics Processing Unit) or more GPU-intensive rather than CPU-intensive to deliver native-like performances.

Strong Community:

You will easily find resources, hire react native developers, and leverage a huge ecosystem of React to build mobile apps. It is powered by Facebook and the community that has poured constant efforts and contributions to make React Native the best framework for developing mobile apps.

Faster Development:

React Native is a great choice for creating high-quality, native-like user experiences without compromising quality and functionality. It reduces load time, offers platform consistency, and smooth UIs, making app development quicker. Since only one codebase is used for different platforms, a large amount of code can be reused. This makes app development faster compared to other approaches.

Let’s see how much you can earn if you are a React Native developer in different parts of the world.
