One typical issue you will get into if you do jQuery is, After importing the jQuery plugins they will register for onClick events, and by that time you can't guarantee that the actual DOM Element is ready, elements may get created later and may get refreshed.

One way of solving the issues is call the jQuery code which does the initialization in componentDidMount() and also in componentDidUpdate() so that you can make sure the DOM elements are present before the jQuery plugin register them.
