How to Extract Values from a JSON String in JavaScript?

Parsing JSON Strings in JavaScript [Resolved]

Question:

How to extract values (result and count) from a JSON string in JavaScript?

Response:

The JSON object built into JavaScript can be used to parse a JSON string:

How to Use JSON.parse() to Extract Values:

  1. Declare a JSON string (e.g., var response = '{"result":true,"count":1}').
  2. Use JSON.parse() to convert the string into a JavaScript object (e.g., const resultObject = JSON.parse(response)).
  3. Access the desired properties within the object (e.g., resultObject.result and resultObject.count).

Example:

var response = '{"result":true,"count":1}'
const resultObject = JSON.parse(response);
console.log(`result: ${resultObject.result}, count: ${resultObject.count}`);

// Output:
// result: true, count: 1

Using this approach, you can easily extract key-value pairs from JSON strings and manipulate the data in your JavaScript code.
