React's model is very similar to how 3D applications work at a high-level. There is a render loop that is either on-demand or continuous, the latter is more common in 3D. During each iteration, input is collected, background processes are run like AI, etc. and they all change the state of the application's data. The new state is given to the rendering engine, and the rendering engine re-renders the entire scene as efficiently as possible.
It turns out it is a lot easier to program dynamic 3D scenes using this method, rather than trying to do two-way binding like Angular, JQuery, etc do. And the performance is typically better too. Imagine trying to do two-way binding in a AAA game with 1,000s or even 100,000s of individual objects in a scene. It would be a programming nightmare! Instead much of the effort is spent trying to reduce the amount work the GPU has to do when rendering the entire scene such as occlusion culling, distance-based level of detail, etc. React's virtual DOM renderer is also trying to render the scene (DOM) as efficiently as possible. But admittedly it is much simpler than Unreal Engine's renderer, but the high-level concept is similar.
I think this is why React feels so natural to so many people when building dynamic web UIs compared to JQuery, Angular, and even Vue.
