As per Wikipedia : In computing, JavaScript Object Notation or JSON (/ˈdʒeɪsən/ JAY-sən) is an open-standard file format that uses human-readable text to transmit data objects consisting of attribute–value pairs and array data types (or any other serializable value). It is a very common data format used for asynchronous browser–server communication, including as a replacement for XML in some AJAX-style systems. JSON is a language-independent data format. It was derived from JavaScript, but as of 2017 many programming languages include code to generate and parse JSON-format data. The official Internet media type for JSON is application/json. JSON filenames use the extension .json. Douglas Crockford originally specified the JSON format in the early 2000s; two competing standards, RFC 8259 and ECMA-404, defined it in 2017. The ECMA standard describes only the allowed syntax, whereas the RFC covers some security and interoperability considerations. A restricted profile of JSON, known as I-JSON (short for "Internet JSON"), seeks to overcome some of the interoperability problems with JSON. It is defined in RFC 7493.
