Frequently asked questions about React Native

Created by Facebook, React Native is an open-source-based mobile application framework that uses only JavaScript, making it capable of supporting both Android and iOS platforms. React, also known as React.js, saves time and effort for developers since they only need one programming language. The Native element allows developers to create JavaScript components to design software programs that run on various devices and platforms, such as smartphones, smart TVs, and laptops. With React Native, developers use the same concepts used in the original React framework to design a rich mobile user interface (UI) for various environments from existing components.
Businesses that want to create mobile apps for iOS and Android simultaneously to ensure a seamless rollout need developers with a background in React Native. Careers in mobile app development that rely on React Native can count on professionals who can design and build stunning UIs in multiple platforms since it works hand-in-hand with platforms like Windows and tvOS. React Native developers are also vital to helping iOS, and Android companies update and otherwise modernize their apps with features like push notifications and animation for better effectiveness for mobile app subscribers. Developers with a background in React Native might work in full-stack development, designing and refining web-based games, websites, mobile apps, and more.
Google Flutter offers developers a UI toolkit that has some similarities to React Native. Flutter also has a native component and compiles web, mobile, and desktop applications from a single collection of source codes. Relying on existing code, Flutter is also a free and open-source framework for developers. Until this point, the two frameworks might sound similar. However, React Native is based on and only uses JavaScript, while Flutter only has a loose connection to the language. Google Flutter primarily uses a new language called Dart. Other differences between the two involve sourcing the tool itself and the installation process, setup and configuration, UI component and development, and community support.
