JQuery is manipulating HTML DOM. But, React Native have DOM-like native view which is not same as HTML DOM.

React Native is NOT an HTML app like Cordova. The only common part between the Cordova and the React Native is the Javascript Engine. Since there is no HTML and CSS, JQuery can't manipulate anything in React Native.

Absolutly not. In React-Native you don't have a DOM like on a web page.

And when using React, you don't need jQuery anymore, or perhaps in some very specific cases but it doesn't seem relevant to me.
