The Inventory Aggregator

Write a function groupInventory(items) that takes an array of item objects. Each item has a name and a category. Your function should return a single object where the keys are the categories, and the values are arrays of item names belonging to that category.

Constraint: You must use the Array.prototype.reduce() method. Do not use a for loop or forEach.

Test Cases:
const items = [

{ name: "Apple", category: "Fruit" },

{ name: "Carrot", category: "Vegetable" },

{ name: "Banana", category: "Fruit" },

{ name: "Broccoli", category: "Vegetable" }

];

groupInventory(items);

Should return:

{

Fruit: ["Apple", "Banana"],

Vegetable: ["Carrot", "Broccoli"]

}

groupInventory([]); // Should return {}
