How to Parse JSON in JavaScript?

Parsing JSON (JavaScript Object Notation) data in JavaScript involves converting a JSON string into a JavaScript object. Consider the following JSON response:

var response = '{ "result": true, "count": 1 }';

To access the result and count values from this JSON string, you can use the JSON.parse() method:

const response = '{ "result": true, "count": 1 }';
const jsonObject = JSON.parse(response);

console.log(jsonObject.result); // true
console.log(jsonObject.count); // 1

The JSON.parse() method converts the JSON string response into a JavaScript object named jsonObject. This object can then be used to access the individual properties jsonObject.result and jsonObject.count as needed.

Example:

const json = '{ "fruit": "pineapple", "fingers": 10 }';
const obj = JSON.parse(json);

console.log(obj.fruit, obj.fingers); // pineapple, 10

Note: The JSON.parse() method is supported in all major browsers and Node.js. It is a convenient and efficient way to parse JSON data and extract its values into JavaScript objects.
