Clojurians Log v2

anyone know why the following throws an error

(rum/defc repeat-label [n text]
  [:div (repeat n [:.label text])])
;; throws "Objects are not valid as a React child"

(rum/defc repeat-label [n text]
  [:div (vec (repeat n [:.label text]))])

totally unexpected for me, from what I’d expect vec version shouldn’t work :)

is vec the correct way to coerce a lazy sequence to a vector? (into [] (repeat n [:.label text])) also works

yes. The thing is, vectors are supposed to be tags and have special meaning when parsed, and anything sequential that’s not vector is supposed to be “list of stuff”

maybe report to sablono? I suspect it’s their compiler

can’t I also pass a vector of tags? e.g. [:ul [[:li "one"] [:li "two"]]]?

which is what I assumed (vec (repeat 2 [:li "thing"])) was doing

though [:ul (map (fn [n] [:li n]) (range 5))] does work, so don’t know what the issue w/ repeat is. ran into this while working on the tutorial in the README.

no, it must be [:ul (list [:li "one"] [:li "two"])]

because vectors are reserved for tags
