How should I store JSON in redis?

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');
