Exploring the World of JSON

What is JSON and how is it structured?

JSON (JavaScript Object Notation) is a lightweight data-interchange format that is easy for humans to read and write and easy for machines to parse and generate. It is structured as a collection of key-value pairs.

Answer:

JSON stands for JavaScript Object Notation, which is a popular data format used for exchanging information over the web. It is often used to transmit data between a server and a web application, as it is easy for both humans and machines to understand.

JSON is structured as a collection of key-value pairs, where each key is a string enclosed in double quotation marks, followed by a colon, and then a corresponding value. The key-value pairs are separated by commas, and the entire JSON object is enclosed in curly braces.

For example:

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

In this JSON object, "name", "age", and "city" are the keys, and "John", 30, and "New York" are the corresponding values. The keys and values can be strings, numbers, objects, arrays, booleans, or null.

JSON is commonly used in web development for transmitting and storing data. It is a versatile and widely accepted format that has become an essential part of modern web applications.
