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).

>> jsondecode('{ "foo": 1, "bar": [10, "apples"] }')
ans = 
  struct with fields:
 
    foo: 1
    bar: {2×1 cell}
>> jsonencode(ans)
ans =
{"foo":1,"bar":[10,"apples"]}
