# json top-level constant

const json = const JsonCodec()

An instance of the default implementation of the JsonCodec.

This instance provides a convenient access to the most common JSON use cases.

Examples:

    var encoded = json.encode([1, 2, { "a": null }]);
    var decoded = json.decode('["foo", { "bar": 499 }]');

The top-level jsonEncode and jsonDecode functions may be used instead if a local variable shadows the json constant.

## Implementation

    const JsonCodec json = JsonCodec()
