Script Preparation code:

// Bereite eine globale Test-Map mit 50 Einträgen vor
const LIST_CACHE = new Map();
for (let i = 0; i < 50; i++) {
    const itemMock = { id: `item_${i}`, maxStack: 99, isUnique: false };
    LIST_CACHE.set(itemMock, Math.floor(Math.random() * 10) + 1);
}

// Minimaler Mock für die #has Methode des Inventars (gibt immer true zurück, um reinen Schleifen-Overhead zu messen)
const inventoryMock = {
    has: function(item, count) {
        // Simuliere minimale Logik, damit der JIT die Schleife nicht wegoptimiert
        return item.maxStack > 0 && count > 0;
    }
};

Tests:

entries()
let allItemsMatch = true; for (const [item, count] of LIST_CACHE) { if (!inventoryMock.has(item, count)) { allItemsMatch = false; break; } }
forEach()
let allItemsMatch = true; LIST_CACHE.forEach((count, item) => { if (!allItemsMatch) return; if (!inventoryMock.has(item, count)) { allItemsMatch = false; } });
keys() + get()
let allItemsMatch = true; for (const item of LIST_CACHE.keys()) { if (!inventoryMock.has(item, LIST_CACHE.get(item))) { allItemsMatch = false; break; } }
