What is Json ??
JSON (JavaScript Object Notation) is a lightweight data-interchange format that is used to transmit data between servers and web applications. It is based on a subset of the JavaScript programming language and is designed to be easy for humans to read and write and easy for machines to parse and generate.
JSON data is represented as key-value pairs, where the key is a string and the value can be any JSON data type, including objects, arrays, numbers, strings, booleans, and null. JSON objects are enclosed in curly braces {}, while JSON arrays are enclosed in square brackets [].
Usage :
JSON is widely used in web applications and APIs as a data exchange format due to its lightweight, easy-to-read syntax and flexibility. Many programming languages provide built-in support for parsing and generating JSON data, making it easy to work with in a variety of contexts.
