var redis = require("redis");
var client = redis.createClient();

js = {
"like":"macdn",
"hate":"kfc"
};
//client.set("foo_rand000000000000", "some fantastic value2");
client.set("foo_rand000000000000", JSON.stringify(js));
client.get("foo_rand000000000000", function (err, reply) {
console.log(reply.toString());
});
client.get("dislike", function (err, reply) {
if (err)
console.log(err);
else
console.log(reply.toString());   
client.end();
});
console.log ('eee');


var redis = require("redis");
var client = redis.createClient();

client.get("foo_rand000000000000", function (err, reply) {
console.log(reply);
js = JSON.parse(reply);
console.log( js.like );
console.log( js.hate );
client.end();
});
console.log ('eee');
