React Native:
React Native is a JavaScript framework for writing native mobile applications for iOS and Android. It uses the same design as React, letting you compose a rich mobile UI from declarative components. It is built on top of the React library and is maintained by Facebook.
Example:
Using React Native, you can create a mobile application that looks and feels native on both iOS and Android. For example, you can create a simple to-do list app that has a native look and feel on both platforms.
NativeScript:
NativeScript is an open-source framework for building native mobile applications using JavaScript, TypeScript, or Angular. It provides a native UI for building mobile applications, and allows developers to access native platform APIs directly from JavaScript code.
Example:
Using NativeScript, you can create a mobile application that looks and feels native, but with a single codebase. For example, you can create a shopping app that has a native look and feel on both iOS and Android.
