JSON (JavaScript Object Notation) is a way of expressing information.[1] JSON is usually easy to understand. It can express information like XML. It is based on JavaScript's notation for object literals.[2] However, JSON is stricter.[2]

JSON and XML are both often used in AJAX.[3] Even though JSON is named after JavaScript, it can be used in other programming languages, such as Python (PHP, etc.)[4]
