node.js - How do I find out the total number of items in a collection? mongoose

Question

I have 100 items in the collection, each item has a "money" field, I need to get the total amount of money from all, preferably without crutches. i don't know how to did it.

const allMoney = async () => {
    let count = 0;
    await User.find({}).sort({ money: -1 }).forEach(plr => { count+=plr.money });
    return count;
}

"user is my model"

Replace your forEach with reduce

Here an example how you can use it. To do a snippet I used some dummy values.

let collection = [4, 3, 2, 1, 5, ,6 ,7]

let result = collection.reduce((acc, val) => {
acc += val;
return acc;
}, 0)

console.log(result);
