JQuery is a great set of tools to make websites more interactive with JS.

react is a compiles-to-plain-js framework for building data heavy complex applications in the web browser.

React has its own template language built into your functions, quite opinionated data flow paradigms, and tries to abstract all of the direct attacking the DOM away into passing pure data around.

JQuery gives you better tools for hitting the DOM, but still is just a set of tools, not a development methodology.

This is simplified, obviously, but trying. :-)
