I’ve got a couple of decimal objects created via decimal.js-light

danielneal14:09:48

They compare equal with (.equals a b) but not with (= a b)

danielneal14:09:10

is there anyway I can make the extend the cljs equality to these objects?

danielneal14:09:49

ah, can I use https://cljs.github.io/api/cljs.core/extend-type with IEquiv?

purrgrammer14:09:28

yep, see an example in https://funcool.github.io/clojurescript-unraveled/#comparison

purrgrammer14:09:16

there is IEquiv for equality and IComparable for comparison (ordering)

awesome thanks

was suprisingly difficult to search for

How much am I foot-gunning myself by monkey patching https://firebase.google.com/docs/reference/js/firebase.firestore.Timestamp to support .getTime? It’s really annoying that these objects do not support .getTime…

delaguardo17:09:33

why not https://firebase.google.com/docs/reference/js/firebase.firestore.Timestamp.html#todate ? and then .getTime ?

martinklepsch17:09:58

@U04V4KLKC because it forces me to handle these dates separately from native dates. The other alternative is to prepare the data containing those dates but I kind of wanted to avoid that

It’ll be fine until it isn’t :)

dazld17:09:11

Think you got all the places where it makes those objects?

dazld17:09:09

not sure what your code looks like, but a helper function might be a bit less fragile
