Answers to Frequently Asked Questions:
JSON (pronounced like the English given name Jason), which stands for “JavaScript Object Notation”, is a lightweight computer data interchange format.
JSON is a subset of the object literal notation of JavaScript, but its use does not require JavaScript. It is a general-purpose, text-based, open standard designed for human-readable data interchange.
JSON’s simplicity has resulted in its widespread use, especially in the development of web applications.
Despite its relationship to JavaScript, JSON is language-independent, with parsers available for many languages. In JavaScript, JSON can be parsed trivially using the eval() function.
JSON is now a formal international data processing standard (October 2013).
