Flattening an Array of Objects in JavaScript: A Step-by-Step Guide

Working with arrays of objects can sometimes be challenging, especially when you want to transform the data structure for better usability. In this post, we'll address a specific problem: how to flatten an array of objects while breaking down its contents into a more manageable format.

The Problem at Hand

Imagine you have an array that looks like this:

The Solution

To achieve this transformation, we will utilize JavaScript's ES6 features, specifically the forEach method. Below is a detailed breakdown of the solution:

Step 1: Define Your Initial Array

Start by storing your initial data in a variable. This is typically how your data might be structured:

Step 2: Create a New Array for Flattened Data

Next, we will create a new array arr2 that will hold the flattened structure, starting with the primary product.

Step 3: Loop Through the List of Products

We now need to iterate through the list_of_products array inside the primary product object. For each product, we will push a new object into arr2 with the appropriate id and value.

Using the forEach method allows us to do this neatly:
