What is react native?

React native is the next generation of react, a Javascript library used by Facebook and Instagram. Mobile developers use it to build native mobile apps because you can reuse components across multiple platforms. It’s a cross-platform framework that allows us to deliver our android & iOS apps faster and involves more of our team’s JavaScript skills.

Why build in react native?

To understand why React Native is so useful, one must understand the two basic ways of building mobile apps:

Native apps – Native apps are apps written in native code – Java for Android and Objective-C or Swift for iOS. They tend to perform best but are expensive to build due to each operating system requiring a dedicated build.

Hybrid apps – Hybrid apps are Phone apps that contain a browser view. They are cheaper to build because they only require to build for both iOS and Android. However, hybrid systems use HTML & CSS to simulate native components, often resulting in poorer performance.

React Native allows developers to build apps for both iOS and Android while sharing common code. This can prove particularly cost-effective while performing as well as native apps in most cases. 

Can existing native code be integrated into a react native app?

Yes, react native supports the integration of existing native code written in Java (for android) and objective-C/Swift (for iOS) through native models and bridging mechanisms.

Is it possible to update and maintain react native apps easily?

Yes, react native apps can be easily updated and maintained since changes made to the codebase can be instantly reflected in the running app through the hot-reloading feature.
