How to Merge Data from Two Different JSON Files in ReactJS

In today's data-driven world, merging information from different sources is a common task. If you're working with ReactJS and have two JSON files containing related information, such as product details and prices, you may find yourself needing to sync this data for your application. In this guide, we'll walk through how to merge data from these two JSON files effectively.

Understanding the Problem

Suppose you have two JSON files:

First JSON File: Contains product information.

Your goal is to combine these two files based on the id so that you can display complete product information (including the price) in your UI.

Step-by-Step Solution

Here's how you can achieve this in a ReactJS environment:

Step 1: Parse the JSON Files

First, parse the JSON data into JavaScript objects, so you can work with them easily. Assuming you have the JSON data as strings, you can do this:
