JSON, which stands for "JavaScript object notation", is a lightweight data interchange format.
JSON and JavaScript
Unlike many object-oriented programming languages, JavaScript objects do not necessarily have to be created by a constructor. JavaScript objects can be created by an object literal format. For example:
my_object =
{ "name" : "Joe Blow"
, "address" : "123 Somewhere Street"
, "city" : "Surrey"
, "province" : "BC"
, "country" : "Canada"
};
This produces a JavaScript object named "my_object" with fields: "name", "address", "city", "province", and "country". One could use this object as follows:
document.write("My name is "+my_object.name+".\n");
document.write("And I live on "+my_object.address+" in "+my_object.city+".\n");
Which would print out:
My name is Joe Blow. And I live on 123 Somewhere Street in Surrey.
JSON is a JavaScript object literal.
JSON Pronunciation
