+## Laravel Tip 💡: Select Sub-Arrays ([⬆️](#helpers-tips-cd-))

+
+There will be times when you need to extract a sub-array from the main one, whether it's from a JSON response, your models, or whatever. While you could use "map" for that, Laravel ships with a much more elegant helper, "select", just for this 🚀
+
+```php
+<?php
+
+use App\Models\Product;
+
+// Instead of this 🥱
+Product::all()->map(
+    fn(Product $product) => collect($product)->only(['name', 'price'])->toArray()
+);
+
+// You can do this instead 🔥
+Product::all()->select('name', 'price');
+
+/**
+ * Reminders:
+ * - pluck() only works for a single key
+ * - only() can't handle nested arrays
+ */
+```
