Grouping Objects in JavaScript: An Easy Guide

When working with complex data structures in JavaScript, one of the most common tasks is to group objects by a specific key. In this guide, we'll address a specific question that many newcomers face: How do I group objects by the product field and filter by it in other fields like keyResults and metrics?

The Problem Statement
