I am currently trying to recreate this tutorial in jsaddle-warp (via obelisk ~~> reflex) and have the line
data' :: Maybe [Int] <- fromJSVal =<< frame ^. js "data" -- frame.data :: Array
liftIO $ print data'
And this works beautifully when compiled with GHCJS but takes over 5 minutes and destroys the entire DOM on jsaddle-warp. **Is there some way to work with massive arrays that is performant on all runners?
I know I could I just do an eval statement but would mainly just like to know the best way to work with massive arrays (this being of length 518400). I also noticed that there isn't a method to update an Array A, at index I.
NOTE: a simple shrug that I'm on my own here would suffice, but hey might as well ask.
