What exactly does the development of React Native apps mean?

React Native is a JavaScript framework that allows developers to build mobile apps for iOS and Android using a single codebase. It is based on Facebook’s React JavaScript library for building user interfaces, and allows developers to use the same approach for building mobile apps as they would use for building web apps. This means that developers can write mobile app code in JavaScript and reuse existing code from web projects, making the development process more efficient and cost-effective. Additionally, because React Native uses native components, apps built with it have a similar look and feel to apps built with traditional, platform-specific languages like Swift or Java.
