Flattening Nested JSON Objects in JavaScript: A Simple Guide

Working with JSON data can sometimes feel daunting, especially when you're faced with deeply nested structures that need to be flattened for easier access. If you've ever found yourself needing to simplify complex JSON objects, you are not alone! In this post, we will explore how to flatten nested JSON objects in JavaScript so that you can work with your data more efficiently.

The Problem: Nested JSON Structure

Imagine you have the following JSON structure representing batches of shellfish data:

The Challenge

Your goal is to transform this data so that it has no nested structures. For instance, you want the output to look like this:

The Solution: Using the map Function

To achieve this, we can leverage the power of JavaScript’s map function. Here's a step-by-step guide on how you can flatten your JSON data.

Step 1: Receive the JSON Data

First, you need to wrap your JSON data in a constant variable for easy access. Here’s how you might do it:

Step 2: Flattening the Nested Structures

Now, we will use the map function to iterate over each batch in your JSON array and flatten the structure. Here's the code to achieve that:

Step 3: Explanation of the Code

Identify Keys with name Property: We begin by identifying all keys in the current object that contain a nested object with a name property.

Create a Copy: To avoid mutating the original object, we create a copy using the spread operator.

Replace Nested Values: We then replace the nested object's value with the value of its name property.

Step 4: Display the Result

Finally, you can view your flattened data by logging result to the console:
