Not specifically walking the DOM but doing DOM/UI related stuff with JS is where I sometimes use recursion. This might also be data processing, but that data is often small and shallow enough for stack growth not not matter, because it is typically related to the UI in _some_ way.

I don't typically use JS for heavy computation of large datasets that lend themselves to recursion. The only thing I can think of that is somewhat large is data visualizations and drawing graphs interactively, but there you typically have a matrix or just a flat array.
