. X is not that good.React Features: Advantages:The great thing about 1.React is that it puts forward the novel idea of virtual DOM, and this idea derives from react Native, which is likely to unify web/native development. On the performance side, because of the virtual DOM technique, Reactjs only updates the DOM when calling SetState, and updates the virtual DOM first, then compares the actual DOM with the actual DOM. This process compared to the Ang
