Challenge 2 / 2

You're interviewing new devs who want to join your team. You gave them a task asking to write a code snippet that will cache for an hour a value returned by countActiveStores() method that can be called on the $this->storeManager class property. Unfortunately, only one dev nailed this task, which one?

$cachedValue = $cache->get('active_stores_count', function (ItemInterface $item): string {
    $item->expiresAfter(60 * 60);

    return $this->storeManager->countActiveStores();
});

$countActiveStores = $this->storeManager->countActiveStores();
$cachedValue = $cache->get('active_stores_count', function (ItemInterface $item) use ($countActiveStores): string {
    $item->expiresAfter(3600);

    return $countActiveStores();
});

$cachedValue = $cache->get('active_stores_count', function (ItemInterface $item): string {
    $item->expiresAfter(1);

    $value = $this->storeManager->countActiveStores();

    return $value;
});

$cachedValue = $cache->get('active_stores_count', function (ItemInterface $item): string {
    $item->expiresAfter(60 * 60);

    $value = $this->storeManager->countActiveStores();
});
