In the world of web development, JSON (JavaScript Object Notation) has become the de facto standard for exchanging data between servers and clients. Whether you’re building a dynamic web application or integrating with a third-party API, understanding how to work with JSON data in JavaScript is an essential skill.

JSON is a lightweight, human-readable data format that represents data as key-value pairs. It is incredibly versatile and can be used to represent virtually any type of data, from simple arrays to complex nested objects. In this article, we’ll explore how to access and manipulate JSON data in JavaScript, providing practical examples along the way.

const jsonString = '{"name":"John Doe", "age":30, "city":"New York"}';
const person = JSON.parse(jsonString);
console.log(person.name); // Output: "John Doe"

In this example, we define a JSON string and use JSON.parse() to convert it into a JavaScript object…
