# JS
db=[]
fs=require('fs')
fs.writeFileSync('db', JSON.stringify(db))
db=JSON.parse(fs.readFileSync('db'),'utf8')

# PHP #
$db=array();
file_put_contents('db',json_encode($db));
$db=json_decode(file_get_contents('db'),true);

# Ruby #
require "json"
db=[]
File.write "db.json", db.to_json
db=JSON.parse open("db.json").read

# Python #
import json
db={}
db['thing']=[]
db['thing'].append({'id': 4123, 'color': 'green'})
with open('db.json', 'w') as outfile:
    json.dump(db, outfile)
