Understanding the Problem

You may have encountered a situation where the JSON data you're working with is deeply nested. For instance, consider the following JSON structure:

In this structure, we want to extract:

The ID from CVE_data_meta

The value from description_data

The exploitabilityScore, severity, and impactScore from the impact

Solution Overview

In order to fetch and display this data in a React component, follow these steps:

Fetch the Data: Use Axios to retrieve the JSON data from the server.

Set the Data to State: Store the fetched data in the component's state using useState.

Render the Data: Map through the JSON structure and extract the required properties to display them in the component.

Step-by-Step Implementation

Step 1: Fetch Data Using Axios

You can retrieve the JSON data from your API endpoint with a simple Axios call.

Step 2: Extract the Required Data

Once the data has been fetched, you can access the nested properties using JavaScript optional chaining, ensuring you prevent errors from undefined data.

Step 3: Render the Data in a Table

In your React component's return statement, render the data in a user-friendly format, like a table:
