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).

 
USING: json.writer json.reader ;
 
SYMBOL: foo
 
! Load a JSON string into a data structure
"[[\"foo\",1],[\"bar\",[10,\"apples\"]]]" json> foo set
 
 
! Create a new data structure and serialize into JSON
{ { "blue" { "ocean" "water" } } >json
