Both the above mentioned frameworks are used for mobile application development in iOS and Android. Mobile app development in New York is creating high-end apps, with React Native and Native Script. What makes them different from each other is the approach that is used for app’s performance, its architecture and programming languages.
Architecture
Changes to the UI are calculated on a UI thread in React Native, resulting in responsive User Interfaces. On the other hand, if you want to access native APIs, you'll need to know Objective-C for iOS and Java for Android. In NativeScript, developers use the UI thread to perform the user interface. Other advantages of this framework include easy access to native APIs, fluid animations, and OS release zero-day support.
Programming languages
Typescript is used as a primary programming language by Native Script for writing codes while React Native uses programming languages like JavaScript, Kotlin, Objective-C, and Swift. Since react native uses several languages, it used each of them for a specific purpose.
Performance
NativeScript and React Native are both capable of delivering native app performance. At runtime, both of them have a fast loading time (60 frames per second). When it comes to native mobile performance, however, there are two major differences between NativeScript and React Native:
Difference 1: Thanks to the Virtual DOM, React Native renders UI quicker than NativeScript.
Difference 2: React Native has a lead over NativeScript in terms of native performance.
Endnote
In terms of native performance and development process, React Native beats NativeScript. Another advantage of this framework over NativeScript is that it can be used to create huge programs with complicated business logic.
I was surfing net and fortunately came across this site and found very interesting stuff here. Its really fun to read. I enjoyed a lot. Thanks for sharing this wonderful information. WordAi Review
