Script Preparation code:

function generateUUIDs(n) {
    const uuids = [];
    for (let i = 0; i < n; i++) {
        uuids.push(crypto.randomUUID());
    }
    return uuids;
}

// Example usage:
const numberOfUUIDs = 10000;
var uuids = generateUUIDs(numberOfUUIDs);

Tests:

String Set
const set = new Set() for (let index = 0; index < uuids.length; index++) { const uuid = uuids[index] set.add(uuid) } for (let index = 0; index < uuids.length; index++) { const uuid = uuids[index] set.add(uuid) }
Index Set
const set = new Set() for (let index = 0; index < uuids.length; index++) { set.add(index) } for (let index = 0; index < uuids.length; index++) { set.add(index) }
Index Set with alignment
const set = new Set() for (let index = 0; index < uuids.length; index++) { const uuid = uuids[index] set.add(index) } for (let index = 0; index < uuids.length; index++) { const uuid = uuids[index] set.add(index) }
