The Problem

Consider the following scenario: you have a JSON object that contains data formatted with HTML tags. When attempting to render this data, the HTML elements show up as raw code instead of appearing as styled text. For example:

[[See Video to Reveal this Text or Code Snippet]]

When displaying this data on the page, the Head property is rendered as <strong>Heading Content</strong> sub-heading, instead of showing the bold heading. This leads to an undesirable user experience where the content does not appear as intended.

The Solution

To display the JSON data correctly, you need to make a couple of adjustments in your React component. Here’s a step-by-step guide to render the data properly.

Step 1: Naming the Array Correctly

First, it’s essential to name your array correctly. Since you intend to work with multiple objects, the array should be named Papers (with an 's' at the end) instead of Paper. This makes it clear that it is an array containing multiple paper objects.

Step 2: Access the Property Correctly

When mapping over the array to render the content, ensure that you specify the correct property. You will want to access the Head property of each Paper object.

Step 3: Use dangerouslySetInnerHTML

The next crucial step is to utilize React's dangerouslySetInnerHTML feature. This allows you to set HTML directly within your React components while ensuring it gets rendered properly. Here’s how to update your code:

Example Code Structure

Putting all these pieces together, your final React component that correctly prints the JSON data with HTML formatting would look something like this:

Important Note

Keep in mind that Papers is not standard JSON format; instead, it is an array of objects in JavaScript. Always ensure you are using the right data types in your React applications to avoid runtime errors and unexpected behavior.
