Introducing JSON

JSON, or JavaScript Object Notation, is an open format for transferring data. It derives from the JavaScript language and is a popular alternative to XML because it’s lightweight and easily human-readable. Here’s what it might look like: { “name”: “John”, “surname”: “Smith”, “age”: 42, “address”: “Dent Street, Gallifrey”, “postal code”: “6900”, “tags”: [“time”, “traveller”] }
