What is JSON and how is it structured?

JSON stands for JavaScript Object Notation. It's a lightweight data interchange format that's easy for humans to read and write, and easy for machines to parse and generate. JSON is structured as key-value pairs, similar to a dictionary.

Can you give me an example of a JSON object?

Sure! Here's a simple example of a JSON object:

{
  "name": "John",
  "age": 30,
  "city": "New York"
}

What are the main data types used in JSON?

The main data types in JSON are strings, numbers, objects, arrays, booleans, and null. For example, a string is enclosed in double quotes, while an object is enclosed in curly braces.

How do I parse JSON in JavaScript?

In JavaScript, you can parse JSON using the JSON.parse() method. For example:

const jsonString = '{"name":"John","age":30}';
const jsonObject = JSON.parse(jsonString);
console.log(jsonObject);
