Golo includes the JSON Simple library to provide JSON support.

While json-simple only supports encoding from lists and maps, this API brings support for sets, arrays, Golo tuples, dynamic objects and structs.

Given a simple data structure, we can obtain a JSON representation:

let data = map[
  ["name", "Somebody"],
  ["age", 69],
  ["friends", list[
    "Mr Bean", "John B", "Larry"
  ]]
]
let asText = JSON.stringify(data)

Given some JSON as text, we can get back a data structure:

let data = JSON.parse(text)
println(data: get("name"))

The gololang.JSON module also provides helpers for JSON serialization and deserialization with both dynamic objects and structs.
