Problem Statement

Load a JSON string into a data structure.
Also, create a new data structure and serialize it into JSON. Use objects and arrays (as appropriate for your language) and make sure your JSON is valid (https://jsonformatter.org).

Let's start with the solution:

use JSON::Tiny;

say from-json '{ "foo": 1, "bar": [10, "apples"] }';
say to-json   %( blue => [1,2], ocean => "water" );
