lib/selectors/chat-selectors.js
622–623 ↗	(On Diff #23988)	These two can be combined to reduce one array pass. Note that the callback you pass to `useSelector` will be executed any time any data in Redux changes, so it's a good idea to prioritize performance here (Flow needs the `Boolean` pass to be separate however)
626 ↗	(On Diff #23988)	This isn't exactly identical, but I think it works here

lib/selectors/chat-selectors.js
624–625	Personally I think this condition is more clear if you start by checking `message.type`, since most message types don't have `message.targetMessageID`

Removed 'Edited' label from the pending thread to match D7141 changes

Removed accidentally added empty line

lib/selectors/chat-selectors.js
606–628 ↗	(On Diff #24267)	This is a very expensive calculation, since you go through every single message in the `MessageStore` for this thread As mentioned above: Note that the callback you pass to useSelector will be executed any time any data in Redux changes I think it would be good here to pull this out of the `useSelector`, and put it in a `useMemo` below. That way, if the underlying data (`containingThread.messageIDs`?) doesn't change, then the calculation will not have to be run again I'm not sure this is possible in this case, but I suspect it is. Can you think of a good `useMemo` we can pull out of this?

606–628 ↗	(On Diff #24267)	I added it as a follow-up task: https://linear.app/comm/issue/ENG-3563/add-usememo-to-pending-thread-edit-messages

"Add useMemo" isn't a good follow-up task, please respond to the diff comments here directly

598 ↗	(On Diff #24386)	In the codebase we typically do `import * as React from 'react';` and then do `React.useMemo` here
