=== JSON Support ===

The language provides support for working with JSON values. The builtin type `json` is defined as the following union: ()|boolean|int|float|decimal|string|json[]|map<json>

<syntaxhighlight>

import ballerina/io;

public function main() returns error {

// Syntax for `json` object values is very similar to the syntax of JSON

json person = {name: "John Doe", age: 25};

// Serialized `json` values conforms to the JSON specification

io:println(person);

// The fields of the `json` value can be accessed as follows

string name = check person.name;

int age = check person.age;

}
