[ClojureScript] defonce to undefined
(defonce foo js/undefined) => nil (defonce foo 1) => 1 I put my initialization code to init! and did (defonce _ (init!)) to be called only once. But incidentally, init! called a javascript function that returns nothing(undefined) as the last statement, and init! ran every time I evaluate it!

Re: [ClojureScript] Best way to write React Native ui in cljs?
Hey Daniel, My guess is that nobody is working on this yet, at least for use with Om. I'm also curious as to whether om.next will ultimately be required (and whether this matters).

[ClojureScript] Best way to write React Native ui in cljs?
Hiccup/sablono has been the gold standard for html; is there anything similar for React Native elements?

[ClojureScript] wanted to do om.core/transact! with -> form (newbee)
I was trying to use something like this (cond-> {:foo bar} bar
(om.core/transact! data :state #(conj % {:foo bar})), the last map should be
passed value, appreciate any help for doing it

[ClojureScript] Inconsistent handling of \space in Clojure & ClojureScript
Your first issue with cljs.reader looks like a bug. Your second issue is because clojure/java has a distinct char type but clojurescript/javascript does not. In cljs, the character literal syntax produces a one-character string, but in clj it produces a 16-bit unsigned int interpreted as a utf-16 character. -- Note that posts from new members are moderated - please be patient with your first post. --- You received this message because you are subscribed to the Google Groups "ClojureScript" group.

Re: [ClojureScript] Om usage questions regarding performance
Thank you David,
so I take it that at some time in the future om can take advantage of transact!
calls with more korks...
If I use swap! on the app-state atom and compare the call to transact! by
logging calls to render I can't validate that render methods are called on all
components or any differences.
Looking forward to om.next :)
Kind regards,
Leon.
