Passing keyword arguments to clojurescript functions from javascript

Question

It's possible to invoke a clojurescript function from javascript, for example:

cljs.core.keyword("foobar")

returns the :foobar keyword, positional arguments work as you would expect. I'm trying to invoke js->clj with the :keywordize-keys argument but so far I haven't been successful. I've tried:

cljs.core.js__GT_clj({'foo': 42}, {'keywordize-keys': true})

// and

var k = cljs.core.keyword('keywordize-keys')
cljs.core.js__GT_clj({'foo': 42}, {k: true})

but neither seem to work as I had hoped. In general how do you specify keyword arguments when calling from js into cljs?

I'm usually going the other way, using clj->js but there appears to be a js->clj that might do the trick: Check out spacjer.com/blog/2014/09/12/clojurescript-javascript-interop — user3810626

In cljs you call the function like this:

(js->clj #js {"foo" 42} :keywordize-keys true)

And the corresponding js code:

var k = cljs.core.keyword('keywordize-keys')
cljs.core.js__GT_clj({'foo': 42}, k, true)
