Using Jquery for dom manipulation is not a good thing in React.
The Shadow dom reflects how the DOM should be at an N moment, and if you change the DOM via jQuery, you 'll disrupt the shadow DOM, and not good things will append there!
You can use jQuery for its utilities but never for dom manipulation, this is why React is here for, and if at a point in time you need jQuery for DOM manipulations, you might have done something wrong before that blocks you to do what you want :)
