JSON

JSON (JavaScript Object Notation) is a lightweight, text-based format used for data interchange. JSON is easy to read and write for humans and simple to parse and generate for machines. Its structure is composed of two elements: objects, containing key-value pairs, and arrays, holding lists of values. Keys in JSON objects are strings, and values can be strings, numbers, arrays, true or false, null, and other objects. This format is widely used in web applications for sending data between clients and servers, as well as in configuration files and data feeds.
