];

bug ❌

list.forEach(item => {
    // 因为： ('INVENTORY_UNION_SLOT' || 'UNION_BOUTIQUE_GAME') === 'INVENTORY_UNION_SLOT'
    // 所以： item.value === ('INVENTORY_UNION_SLOT' || 'UNION_BOUTIQUE_GAME') =>  item.value === 'INVENTORY_UNION_SLOT' ❌
    if (item.value === ('INVENTORY_UNION_SLOT' || 'UNION_BOUTIQUE_GAME')) {
        // console.log('item', item);
        // console.log('?', item.value === ('INVENTORY_UNION_SLOT' || 'UNION_BOUTIQUE_GAME'));
        // console.log('???', (item.value === 'INVENTORY_UNION_SLOT' || item.value === 'UNION_BOUTIQUE_GAME'));
        Object.assign(item, {
            disabled: true,
        });
    };
});

list.forEach(item => {
    if (item.value === 'INVENTORY_UNION_SLOT' || item.value === 'UNION_BOUTIQUE_GAME') {
        Object.assign(item, {
            disabled: true,
