Frequently asked questions

What does a React Native developer do?

A React Native developer builds cross platform mobile apps for Android and iOS using React Native and JavaScript. They build screens and components, connect to APIs, handle navigation and fix bugs. At the entry level they deliver assigned features, test on both platforms and learn React Native and native mobile basics with support from senior engineers.

What is the difference between React and React Native?

React builds user interfaces for the web using HTML elements in the browser. React Native uses the same React ideas to build mobile apps that render real native components on Android and iOS. The programming style is similar, so React knowledge transfers, but React Native adds mobile concerns like navigation, devices and platform differences.

Is React Native good for building mobile apps?

Yes, for many apps. React Native lets one team build for Android and iOS from a shared JavaScript codebase, saving time and cost, and it is popular with Indian startups and product firms. For very heavy graphics or deep platform features, native development can be better, but React Native suits most business and content apps well.
