JSON
text-based open standard designed for human-readable data interchange / From Wikipedia, the free encyclopedia
JSON (JavaScript Object Notation) is a way of expressing information.[1] JSON is usually easy to understand. It can express information like XML.[2] It is based on JavaScript's notation for object literals.[3] However, JSON is stricter.[3]
JSON and XML are both often used in AJAX.[4] Even though JSON is named after JavaScript, it can be used in other programming languages, such as Python (PHP, etc.)[5]
