React vs GWT for large scale web application

Question

As Java developer, I always felt comfortable developing web applications using GWT, but every now and then I am trying to check if there is a better framework that I can use for developing a large scale web application.
I tried out React, and I liked it, but as a Java developer I am not feeling as comfortable developing using JS, and I am scared that when the project will become really big I will have troubles maintaining it, and I will get "spaghetti code".
Basically I wanted to know what are the benefits of React over GWT? and am I right to be scared of big scale projects developed in JS?

Answer 1

Now you could try VueGWT: Github project The idea is to write your control in Java and your views with vueJS templates. We have started (only a few part for now) to use it for GenMyModel, a very big GWT application.
