On swannodette's previous blogpost, he wrote in Reactive style:
(defn ex0-key-events [prevent-default?]
(->> (events js/window "keydown" prevent-default?)
(map key-event->keycode)
(filter KEYS)
(map key->keyword)))
Where did the `events` function (line 2) come from? Does it create a lazy dechunked seq which takes events from a buffered channel? Is it built atop RxJS?
(Sorry, I haven't yet used ClojureScript, only Clojure. Googling didn't help.)
- davidbalbert 13y agoMy JavaScript isn't great, so I'm ignoring prevent-default?, but you can probably do something like this: (defn events [object type] (let [out (chan)] (.addEventListener object type (fn [e] (put! out e))) out))
