This project aims to offer the same translation feature available in Calva, which let you translate snippets of JavaScript into ClojureScript, but in a web page.
The main library, responsible for the transformation is the very same code of Calva itself, you can find the source code here.
So this project is relying 100% on the code of Calva, I just extracted and glued together some things in order to use it as a web app.
Thanks to the people behind Calva for making such a great open source tool to work with Clojure!
