Possible to map of `useSubmissions` result?

I was just playing with solid-router, and was curious if there was a way to map over the results of useSubmissions outside of a rendered <For> component. In the linked code: https://github.com/JacobSNGoodwin/scavenge-solid/blob/main/src/components/HuntItemsList.tsx#L43, I was trying to basically create a list of items where I optimistically filtered out any items being deleted and optimistically added any being added, while also sorting them. I was able to get the ids of submissions being deleted in a good old fashioned for loop, but we cannot map over the Proxied array (which may be fine and desirable). So this had me wondering if anyone has opinions on the best way to handle this sort of situation. I'm probably coming from the react world and not doing this right.

If pressed you can always use the $TRACK symbol (exported by solid-js) to gain access to the core array (with reactivity only to the array as a whole):

const raw = (s: SetCountSubmissionMany) => {
  if($TRACK in s) {
    return s[$TRACK] as SetCountSubmissionMany;
  }
  throw new Error('Not a solid.js Proxy')
}

const raw = (s: SetCountSubmissionMany) => {
  if($TRACK in s) {
    return s[$TRACK] as SetCountSubmissionMany;
  }
  throw new Error('Not a solid.js Proxy')
}

You can do something like this I think. [...submissions.values()].map

Thanks. It will be useful for me to look into the internals to better understand solid-js. This does work! Thanks. I guess this is a way to access the inner array of the proxy, then. This is one I'll definitely want to catelog in the old noggin'
