Using javascript datetime in clojurescript

Question

I want to show date and time in Clojurescript, but anything I tried did not work. Can anyone help with an example? I tried to use JavaScript datatime in different syntax ways, but none of them worked. Thank you.

Update

I tired these but they did not work:

(. (js/Date))
(js/Date.)
(now (js/Date))
(js/Date.new)
(js/Date.new.)
(.new (js/Date)

I just wont to show the current date and time on the screen. Inside a [:h3] tag in the .cljs file.

It's very unclear what you actually want. You write that you tried some things - can you post them? What exactly do you mean by "show date"? If you mean just creating a date as in new Date() in JS, it's (js/Date.) in CLJS. — Eugene Pakhomov

Please add the code you have tried and how it failed (e.g. errors, stacktraces, logs, ...) so we can improve on it. — cfrick

@cfrick I added the things I tried. The problem is I don't know how to use java introp and did not fond anything helpful by searching. — niloofar

@EugenePakhomov should [:h3 (js/Date.)] show the date? Or am I doing that wrongly? — niloofar

(.toLocaleString (js/Date.))
;; => "22/11/2022, 17:17:22"

and in [:h3]:

[:h3 (.toLocaleString (js/Date.))]

If you want other formatting you can mix and match the available methods on a Date instance using interop.
