Array list with 2 values and doing it to a top 10 list - node.js

Question

im working on a Discord bot and have a reputation system with fs (npm package) and saving peoples reps in a file and doing the file name as they discord id
now im working on a top 10 command and would need some help here, i currently have this as code:
let users = [];
let reps = [];
fs.readdirSync('./data/reps/').forEach(obj => {
users.push(obj.replace('.json', ''))
let file = fs.readFileSync(`./data/reps/${obj}`)
let data = JSON.parse(file)
reps.push(data.reps)
})
let top = [...users, ...reps]
top.sort((a,b) => {a - b})
console.log(top)
the files form the users are like this:
{
"users": [
"437762415275278337"
],
"reps": 1
}
users are the current users that can't rep the persion anymore and don't need to use it in the command
i wan to get the top 10 of reps so that i can get the user id and how many reps they have, how could i do it with the code above?

Answer 1

You could try this
const topTen = fs.readdirSync('./data/reps/').map(obj => {
const file = fs.readFileSync(`./data/reps/${obj}`);
const data = JSON.parse(file);
return { ...data, name: obj.replace('.json', '') };
}).sort((a, b) => a.reps - b.reps).slice(0, 10);
console.log(topTen);

Answer 2

I would change how you push the data
const users = [];
fs.readdirSync('./data/reps/').forEach(obj => {
let file = fs.readFileSync(`./data/reps/${obj}`)
let data = JSON.parse(file)
reps.push({ reps: data.reps, id: obj.replace(".json", "") });
})
That way when you sort the array the id goes along with
//define this after the fs.readdirSync.forEach method
const top = users.sort((a,b)=> a.reps-b.reps).slice(0,10);
If you want an array of top ids
const topIds = top.map(e => e.id);
If you want a quick string of it:
const str = top.map(e => `${e.id}: ${e.reps}`).join("\n");
Also you should probably just have one or two json files, one would be the array of user id's and their reps and then the other could be of user id's and who they can't rep anymore
