What is the difference between React State and Javascript objects? when the state changes the dom changes automatically and when objects change the dom is also changed.

React State IS a JavaScript object. The purpose is to keep track of changing information between renders.
The best part is that if you change the state inside a component, the virtual DOM will know which parts of the DOM need to be modified (instead of modify the whole DOM).

In React , The state object is where you store property values that belongs to the component. React is a javascript library so it uses javascript object as its state. In short React state is a javascript object .
When there is any change in the state via the setState func , then the DOM re-renders only to the specific part that has changed. Beauty of react , the virtual Dom.
