Does React Native need native code?

So to summarize React Native is not really a Native framework , but It’s much closer to Native code, than hybrid apps.21 Şub 2018

React components wrap existing native code and interact with native APIs via React’s declarative UI paradigm and JavaScript. This enables native app development for whole new teams of developers, and can let existing native teams work much faster.

Under the hood, React Native uses native components like UIView and UIImageView in iOS and exports them to the JavaScript layer. We use these components in our daily development process.
