JSON is a lightweight data-interchange format that is easy for humans to read and write, and easy for machines to parse and generate. It's based on a subset of JavaScript language but is language-independent, with parsers available for many languages. JSON is primarily used to transmit data between a server and a web application as an alternative to XML. It represents objects with a simple, ordered list of values, and is widely used in web hosting and development for its simplicity and efficiency in structuring data.
