With React Native, we can build mobile apps using only JavaScript. It uses the same design as React, letting you compose a rich mobile UI from declarative components. Using this framework, you don't build a "mobile web app", an "HTML5 app", or a "hybrid app". You build a real mobile app that's indistinguishable from an app built using Objective-C or Java. React Native uses the same fundamental UI building blocks as regular iOS and Android apps. You just put those building blocks together using JavaScript and React.

The Ionic Framework is a complete open-source SDK for hybrid mobile app development. It provides tools and services for hybrid mobile app development using Web technologies like CSS, HTML5, and Sass. Apps can be built with these Web technologies and then distributed through native app stores to be installed on devices by leveraging Cordova.
