<description>
Helper class for parsing JSON data. For usage example and other important hints, see [JSONParseResult].
The [JSON] enables all data types to be converted to and from a JSON string. This useful for serializing data to save to a file or send over the network.
[method stringify] is used to convert any data type into a JSON string.
[method parse] is used to convert any existing JSON data into a [Variant] that can be used within Godot. If successfully parsed, use [method get_data] to retrieve the [Variant], and use [code]typeof[/code] to check if the Variant's type is what you expect. JSON Objects are converted into a [Dictionary], but JSON data can be used to store [Array]s, numbers, [String]s and even just a boolean.
[b]Example[/b]
[codeblock]
var data_to_send = ["a", "b", "c"]
var json = JSON.new()
var json_string = json.stringify(data_to_send)
# Save data
# ...
# Retrieve data
var error = json.parse(json_string)
