On what to write a simple application with figure animation?

Question

Programming

It is necessary to write a simple application in which a figure will be present. It will move around the screen at different speeds (the user sets) and respond to a couple of events.
The question is what to write on. I know Java well and frameworks for it (Spring, Hibernate (and suddenly), GWT).
I was thinking about Java + GWT to make a simple web application. Or write in pure JS from scratch.
BUT, this application will need to be analyzed with tools in the future, a la Doxygen. What would you recommend to write on?

Answer 1

TypeScript should be a good place to go after the experience with Java. Or pure js, yes.
As a library for rendering 3d, you can use threejs, for 2d raphaeljs.
You should not write the client part of a web application in java, js can now do almost everything you need.
Or you can take utilities like Blend4web, on which you can build a simple application with graphics without any code at all.
