如何在原始数据中搜索匹配数据？

Question

Right now, I coded a function to go like this

async function checkPlayerScam(ign) {
    const UUID = await getUUID(ign);
    if(MATCHING){
        playerIsScammer = true
    }
    else {
        playerIsScammer = false
    }
}

The MATCHING is just a placeholder at the moment. I want to check their UUID, and make sure it isn't in this list: https://raw.githubusercontent.com/skyblockz/pricecheckbot/master/scammer.json

Any idea how? It needs to be relatively fast

EDIT: It'd also be cool if I could get the reason from the list, but that's not as necessary

Answer 1

https://lodash.com/docs/#find

Use lodash _.find to

const uuid = '000c97aaf948417a9a74d6858c01aaae'; // uuid you want to find
const scammer = _.find(scammersList, o => o.uuid === uuid);
if (scammer) { // if scammer found
    console.log(scammer);
    console.log(scammer.reason)
}

This function will fetch the data, then check if the uuid 1d0c0ef4295047b39f0fa899c485bd00 exists. Assuming that you already fetched the data somewhere else and stored it, all you need to do is check if a given uuid exists by adding the following line where you please:

!!data[uuidToCheck]

uuidToCheck should be the uuid string that you are looking for. This line will return true if the uuid exists and false otherwise.

In terms of the spacetime complexity, this function runs in constant time [O(1)] and O(N) space. This is the fastest time you can get it to run.

data[uuidToCheck].reason will return the reason.

async function playerIsScammer(uuidToCheck) {
    uuidToCheck = '1d0c0ef4295047b39f0fa899c485bd00';
    const response = await fetch('https://raw.githubusercontent.com/skyblockz/pricecheckbot/master/scammer.json');
    if (response.ok){
        let data = await response.json();
        if(!!data[uuidToCheck])
            return data[uuidToCheck].reason;
        return false
    }
}

For anyone wondering, this is how I solved it:

async function checkPlayerScam(ign) {
    const UUID = await getUUID(ign);
    const response = await fetch(`https://raw.githubusercontent.com/skyblockz/pricecheckbot/master/scammer.json`);
    const result = await responsejson();
    if (result[UUID] = null) {
        playerIsScammer == False
        } 
    else{
        playerIsScammer == True
        }
}
