Note that Code Review requires code to already be working correctly to the best of the author's knowledge. CR is more for broad critiques and suggestions on readability, maintainability, professional conventions, but only on correctness in unexpected edge cases that happen to not have been taken into consideration yet. Asking how (or if) something works is still better suited for SO than CR — CertainPerformance 30 secs ago
Q: Returning a promise with nested conditionals from a Firebase function?

I first return the call to get the document because get() itself returns ...

@SᴀᴍOnᴇᴌᴀ Quality: Ok, On-topic on SO: I think so, Duplicate: Don't know. I don't want to check for a duplicate so I'm not going to vote to migrate, however if you want to and you don't find one I think it's ok.
@Peilonrayz IMO that seems too broad for SO...
I personally don't ever vote to migrate. Not a fan of the system and I'm somewhat aware of my lack of understanding of other site's rules.
@SᴀᴍOnᴇᴌᴀ Then the answer to "is that appropriate" is a definitive "no".

@Peilonrayz Flagged. I hope it doesn't get declined.
@Peilonrayz this is why I was hesitating to flag it. > declined - Using standard flags helps us prioritize problems and resolve them faster. Please familiarize yourself with the list of standard flags: see What is Flagging?
That was from a flag I raised on 9/18.
@pacmaninbw Unless you have a high percentage of declined flags then I wouldn't worry too much about it
11:17 PM
@pacmaninbw I don't have, nor do I want, the context to comment on that. I almost exclusively use custom flags. I wouldn't take it to heart, just try to use the normal flags if they seem apparent from now on.
I have about 10% declined.
Out of 329 helpful flags.
@pacmaninbw I have ~5% but I know the mod's tendencies now and most of my declined are either special cases or because mods have a different POV on the rules. If you check out your flag history page you possibly can see a pattern. If you can see say your VLQ posts are being declined just stop reporting them, if the site then turns into a cesspit because of this it's not your fault.
Wish I could star just this portion - if the site then turns into a cesspit because of this it's not your fault.
