Script Preparation code:

const usableCount = 5;
const itemCount = 10;

const type = Math.floor(Math.random() * 100);
const usables = new Array(usableCount).fill(0).map(_ => Math.floor(Math.random() * 100));
const items = new Array(itemCount).fill(0).map(_ => Math.floor(Math.random() * 100));

Tests:

Nested Join + Join (Join x3)
const key = [type, usables.join(), items.join()].join ("|");
Loop Push + Join (Join x1 with string)
let data = [type, "|"]; const usableCountMinusOne = usableCount - 1; for (let i = 0 ; i < usableCountMinusOne ; i++) data.push (usables[i], ","); data.push (usables[usableCountMinusOne], "|"); const itemCountMinusOne = itemCount - 1; for (let i = 0 ; i < itemCountMinusOne ; i++) data.push (items[i], ","); data.push (items[itemCountMinusOne]); const key = data.join ("");
Simple Join (Join x1 with arrays)
const key = [type, usables, items].join ("|");
Loop Concatenate (string only)
let key = type + "|"; const usableCountMinusOne = usableCount - 1; for (let i = 0 ; i < usableCountMinusOne ; i++) key += usables[i] + ","; key += usables[9] + "|"; const itemCountMinusOne = itemCount - 1; for (let i = 0 ; i < itemCountMinusOne ; i++) key += items[i] + ","; key += items[9];
Template Literal (template literal string with arrays)
const key = `${type}|${usables}|${items}`;
Template Literal + Join (template literal string with join)
const key = `${type}|${usables.join()}|${items.join}`;
Simple Concatenate + Join
const key = type + "|" + usables.join() + "|" + items.join();
