React Native is a framework for building native mobile apps using JavaScript. On the other hand, ReactJS is a JavaScript library used for building user interfaces for web apps. React Native allows developers to create mobile applications that are nearly indistinguishable from apps built with Objective-C or Java. The framework also offers a number of components and APIs that are not available in ReactJS, such as the ability to access device hardware, push notifications, and integration with other native applications. However, if you want to hire a React JS developer for your web application, you can do that to too with Matellio.
