React-Native

React Native is a framework for building mobile applications using JavaScript and React.

It allows us to create real native Android and iOS apps using a single codebase.

Think of it as Write once in JavaScript, run as native mobile apps

Simple explanation

Traditional mobile development looks like this:

Android App → Java / Kotlin
iOS App → Swift / Objective-C

For this we need:

  • Two separate codebases

  • Two different skill sets

  • More time and maintenance

React Native works like this :

React Native App(JavaScript)
↓
Native Android & iOS Components

You write JavaScript + React, and React Native converts it into native UI components.

  • Not a web app
  • Not a hybrid WebView app
  • Real native performance
