Clojurescript - update-in a Javascript map

How do I apply a given function to a JavaScript JSON structure ?

I would like to be able to do the following :

(update-in js-data [.-data] my-fn)  ;; fails since .-data is not valid

update-in and similar functions only work on ClojureScript data structures.

In your specific example you could convert js-data to a ClojureScript data structure like this

(update-in (js->clj js-data) ["data"] my-fn)

If you cannot convert the Javascript object to a plain map you can always modify the original object in-place using set!.

(set! js-data -data my-fn)
