Does React Native have a 'Virtual DOM'?

Question

From ReactJS wiki page about Virtual DOM:

React creates an in-memory data structure cache, computes the resulting differences, and then updates the

Answer 1

Here's an over-simplification: ReactJS outputs the DOM that can be rendered the browsers. As you already know, the virtual DOM helps ReactJS efficiently keeps track of the delta of what has changed. For React Native for iOS, ultimately it outputs UIKit code. Same thing with React Native for Android, but instead of outputting DOM or UI Kit, the output is created using Android SDKs. So virtual DOM is just an intermediate step. It can be considered as a combination of the internal data structure to hold the data that describes where to render the button and textbox, what happens when you tab the button, etc, and an efficient algorithm to keep track what has changed. The same code can be used for all platforms. Only the final step is different. Depending on the platform, it has code that generates the DOM, UIKit code, or whatever name Android UI lib is called.
