You don't need client-side stuff until you do. If all you're doing is simple html form submissions, it doesn't make sense to integrate something like React. But then you need validations, and server-side checks for availability, then dynamic forms based on previous input choices, and data synching to preview the profile on the right, and then - might as well use React or similar instead of jQuery with DOM manipulation.
