Ways to utilize a string as an object?

Hey there! I'm just getting started with software development and currently working on an application using React Native. The backend is sending me a large data set, but here's a snippet of it.

My challenge is that I want to access the first element in the array as data.Terms[0] or use the incoming data with .map. However, whenever I try to do so by using JSON.parse, I end up receiving the error message 

Error: JSON.parse requires at least one parameter

How can I work around this issue to utilize the data in the ways I mentioned above?

import React from "react";
import { View } from 'react-native';

export default Dropdown = ({ }) => {

    const data = {
        "Terms": "[{\"TermId\":\"12\",\"time\":\"10:00\"},{\"TermId\":\"13\",\"time\":\"13:00\"}]"
    }

    return (
        <View>
        </View>
    )
}

Answer №1

It seems like you've got a mix of a JSON object and a JSON string in your data. Remember, you can only parse a JSON string, not a JSON object. To properly read the data, you should follow this code snippet:

const jsonData = {
  "Items": "[{\"ItemId\":\"56\",\"name\":\"Apple\"},{\"ItemId\":\"57\",\"name\":\"Banana\"}]"
}

var itemsArray = JSON.parse(jsonData.Items);
console.log(itemsArray);

var itemName = itemsArray[0].name; // Apple
