Order of object keys is not guaranteed.

json = require('json')
print(json.encode(
    { 1, 2, 'fred', {first='mars',second='venus',third='earth'} },
    { sort_keys=true, pretty=true, indent=4 }))

[

        "second": "venus",
        "third": "earth"
    }
]

Decoding

json = require("json")
testString = [[ { "one":1 , "two":2, "primes":[2,3,5,7] } ]]
decoded = json.decode(testString)
table.foreach(decoded, print)
print ("Primes are:")
table.foreach(o.primes,print)

one		1
two		2
primes		table: 0032B928
Primes are:
1		2
2		3
3		5
4		7

JSONRPC Usage

json = require('json')
require("json.rpc")
server = json.rpc.proxy("http://jsolait.net/testj.py")
result, error = server.echo('Test echo!')
