🔹 Group Products by Category Using DataWeave | Real-World Scenario

In this hands-on DataWeave tutorial, we solve a practical transformation challenge from product management and e-commerce domains:
You receive a flat list of products with their associated categories, and your goal is to group them into separate arrays by category.

✅ Input JSON:

A flat array of product objects with fields product and category
[
{
"product": "iPhone",

},
{
"product": "T-Shirt",
"category": "Clothing"
},
{
"product": "Laptop",
"category": "Electronics"
}
]

✅ Expected Output:

A JSON object where each key is a category, and the value is an array of product names
[
{
"Electronics": [
"iPhone",
"Laptop"
]
},
