Is React Native slower than native?

Although React Native isn’t a mobile app native language, it lets you achieve a performance similar to a truly native app , with the benefits of a framework – increased productivity, faster, easier development. It allows you to optimize your app’s performance by including native code in some areas of your app.

CPU-intensive test (Borwein algorithm) for Android Native is 2 times faster then Flutter. React native is around 6 times slower than native .

Faster developing. React Native is powered with JavaScript. Thus, up to 90% of the code for your mobile app may be taken from web applications. Building iOS apps with React Native is 33% faster than Swift and takes 1,5 months.

Reason #2: What Makes React Native Fast? Another advantage of using React Native is that when you build an application with React Native, it renders “native” mobile UI (as opposed to web views), so your app will run smoother and better.
