I recently hit exactly this question in a ClojureScript app I’m writing. It just so happens that Javascript provides a .indexOf method which is, as near as dammit, the same as the one provided by Java. So in this instance, portability isn’t an issue.
But having said that, I would still prefer to see this supported natively in Clojure, even if it’s just a wrapper around the interop. Using interop to do things that are as generic as simple string manipulation just feels messy. -- paul.butcher->msgCount++ Silverstone, Brands Hatch, Donington Park...

Of course, anyone else is free to create libraries that try to make portability between those two platforms easier. Perhaps someone has already taken a go at creating such a thing? I haven't used ClojureScript myself yet, so haven't looked for anything in that area.
