JavaScript Object Notation, more commonly known by the acronym JSON, is an open data interchange format that is both human and machine-readable.
JSON was specified by Douglas Crockfor in in the early 2000s. It was originally derived from JavaScript, but now supported by many programming languages. Here is a simple example of a JSON document: { "firstName": "John", "lastName": "Smith", "isAlive": true, "age": 25, "address...
For instance, an application written in Java can easily send JSON data to a Python application. Or a mobile app written in JavaScript can use JSON to communicate with a back-end server written in PHP. Why? Because both systems can parse and generate JSON. Beyond web development, JSON is ...
