I have this JSON file I'm making a web request to.

It's an array of JSON objects as you can see and I want to get the object that has a matching hash to. What I have my end goal is to get the upVotes and downVotes from stats.

Here is an individual object example.

Also, I'm trying not to use any for loops if possible since I want as much performance as I can.

Basically, say, in my code, I have a hash

4b2da842b687ec4cfbc948c583c21c79d4120de0

and, I want the object that has that value for the hash in the JSON.

On the command line: `curl https://raw.githubusercontent.com/andruzzzhka/BeatSaberScrappedData/master/beatSaverScrappedData.json | jq '. | map(select(.hash == "4b2da842b687ec4cfbc948c583c21c79d4120de0"))'` – Martin York Jun 17 '20 at 21:19

@Futuremappermydud Does jq actually solve your problem or are you still trying to use c++ to parse the JSON? – Martin York Jun 18 '20 at 01:58
@MartinYork im required to use c++ yes – Futuremappermydud Jun 24 '20 at 19:11
@Futuremappermydud Does this help? https://gist.github.com/Loki-Astari/ee4a2a83de877378bfbca5d3513e31d8 – Martin York Jun 24 '20 at 19:34
@Futuremappermydud: Which loop are you trying to avoid? The loop on array? How are you querying this JSON? Fetch once and query all the up and down votes after? – Azeem Jul 02 '20 at 10:04
