may I ask here for tick library?

I'm on cljs and I've required this tick.locale

but the error stays the same

this is normal?

JS reload failed Error: Locale is nil, try adding a require '[tick.locale-en-us] =(

i believe you have to install the npm js-joda packages: https://www.juxt.land/tick/docs/index.html#_reducing_tick_build_size
