UML or CASE tool to analyze *huge* JavaScript code base?

Question

I have to figure out how a huge JavaScript code base works and I'm wondering if there are any CASE/UML tools to analyze its structure. I understand that there are several limitations because of the dynamic typing and existence of eval(), but I suppose if IDEs can offer meaningful inspections for JavaScript code these days, there must be some way to visualize dependencies, etc.

Answer 1

use JS/UML which is an eclipse plugin from jsuml.org
