When I started TipMe, I thought about using React frontend. At the end, plain, simple jQuery won.
I had to build this iteration of the site fast and by using jQuery I could keep using Django as a full stack development tool. One important point is Django form (combined with Django Bootstrap3) means that I don't have to reinvent form rendering again, which will be the case with React.
Over time, more interactivity seeped into the site and React components start making its way into the codebase.
I now wish the site is built using React so that I could add more user friendly interfaces easier (no more fuddling with server states) but I would still say jQuery helped me get past those early days.
