JSON (JavaScript Object Notation) is a lightweight data-interchange format that's easy for both humans to read and write and for machines to parse and generate. It uses a simple syntax based on key-value pairs and arrays, making it ideal for transmitting data between a server and a client. JSON is language-independent, but its format is derived from JavaScript, making it widely used in web development. It's commonly utilized in APIs for data exchange due to its efficiency and ease of use. JSON's simplicity has made it a preferred alternative to XML in many applications.
