Ionic is a popular hybrid app development framework, not a cross-platform app development framework.

Cross-platform app development frameworks allow developers to build apps for multiple platforms using a single codebase, reducing development time and cost.

React Native's hot reloading feature allows developers to see changes in their code reflected in the running app almost instantly.

Flutter uses Dart as its primary programming language, which is known for its fast compilation and easy-to-learn syntax.

Xamarin allows developers to build native apps for iOS, Android, and Windows using C# and .NET.

Cordova provides access to native device features such as camera, GPS, and accelerometer through its plugins.

React Native uses a declarative UI syntax called JSX, which makes it easy to build complex user interfaces.

Flutter uses a custom rendering engine called Skia, which provides native-like performance on both iOS and Android.

Cordova is primarily used for building hybrid apps, which combine native and web technologies.

Xamarin uses C# as its primary programming language, allowing developers to build native apps for iOS, Android, and Windows using a single codebase.

React Native has a large and active community, with a wide range of libraries, tools, and resources available.

React Native allows developers to build apps with a native-like user experience, thanks to its focus on declarative UI and performant animations.

React Native's hot module replacement feature allows developers to make changes to their code and see those changes reflected in the running app without having to rebuild the entire app.

Xamarin allows developers to build native apps for iOS, Android, and Windows using a single codebase, resulting in native-like performance.

Cordova has a large ecosystem of plugins that allow developers to access native device features and third-party services.
