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).

import "/json" for JSON
 
var s = "{ \"foo\": 1, \"bar\": [ \"10\", \"apples\"] }"
var o = JSON.parse(s)
System.print(o)
 
o = { "blue": [1, 2], "ocean": "water" }
s = JSON.stringify(o)
System.print(s)
