JSON is a data format that is based on a subset of JavaScript.
A simplified version of the specification is available on the JSON homepage. The full specification is available as an IETF RFC.
Libraries exist in many different languages to convert from a string of JSON data into data structures appropriate for that language (and to go the other way). A list of some of them can be found near the bottom of the JSON homepage.
An array is a data structure common to most programming languages which contains a number of variables in a specific order. JSON has an array data type.
A JSON Object is a serialisation of a collection of key/value pairs. Most programming languages have a matching data structure, such as a hash in Perl or a (simple) object in JavaScript.
In the page you link to, there is no mention of JSON. It has a variable (
weatherData) to which is assigned a simple object (using an object literal{}) which has one key (reports) to which is assigned an array (using an array literal[]) that contains a number of objects, each of which consists of a bunch of key/value pairs where the values are all strings.If you were to remove the first line, and the semi-colon at the end, then the example would be a JSON data structure representing the same information. This is because, as I said earlier, JSON is based on a subset of JavaScript and that part of the example conforms to the subset.
