builder

EXPERIMENTAL: Returns a JavaScript Proxy ctor fn with the provided key-fn. Invoking the returned fn on ClojureScript maps and vectors will returned proxied values that can be used transparently as JavaScript objects and arrays: (def proxy (builder)) (def proxied-map (proxy {:foo 1 :bar 2})) (goog.object/get proxied-map "foo") ;; => 1 (def proxied-vec (proxy [1 2 3 4])) (aget proxied-vec 1) ;; => 2 Access patterns from JavaScript on these proxied values will lazily, recursively return further proxied values: (def nested-proxies (proxy [{:foo 1 :bar 2}])) (-> nested-proxies (aget 0) (goog.object/get "foo")) ;; => 1 Note key-fn is only used for proxied ClojureScript maps. This function should map strings to the appropriate key representation. If unspecified, key-fn defaults to keyword. All maps proxied from the same ctor fn will share the same key-fn cache. A cache-fn may be suppled to override the default cache. This fn should take key-fn and return a memoized version.
