How to Dynamically Call JSON Data in React with Strings

React is a powerful JavaScript library used for building user interfaces, especially when dealing with data. However, many developers, especially those new to React, often face challenges when it comes to dynamically calling JSON data. This guide will address a common issue and provide a clear, step-by-step solution.

The Problem: How to Call JSON Data with a String

Imagine you have imported two JSON files, JinData and AsukaData, and you want to display these based on a string value stored in an array. Your initial code may look something like this:

In this code, Data={${element}Data} is attempting to use string interpolation to pass in the corresponding JSON data. However, it incorrectly treats this as a string rather than the desired JSON object. As a result, you won’t get the data you need.

The Solution: Map JSON Objects Properly

The key to solving this issue is to restructure your code so that the JSON data is directly accessible when mapping. Instead of relying on string interpolation, we will create an array of objects that stores both the path and the JSON data.

Step-by-Step Breakdown

Import JSON Files
Make sure you've imported your JSON data files at the beginning of your React component.

Create a Unified Array
Instead of using an array of strings, create an array of objects where each object contains a path and its corresponding data.

Map Over the Unified Array
Use the map function over this new charArray. This way, you can directly access the JSON data through destructuring.

Conclusion

By restructuring your approach to how JSON data is called in React, you can efficiently work with dynamic data without hitting roadblocks. Mapping through an array of objects provides a more straightforward pathway to access data directly, eliminating the confusion that comes from string interpolation.

With these steps, you should be able to handle JSON data dynamically in your React applications with ease. Happy coding!
