Answer 1

See Objects: iterating over properties

for (key in obj) {
  /* ... делать что-то с obj[key] ... */
}

Further ....

var obj = {
3223: {
count: 112,
popular: true,
price: 2,
id: 1,
service: "Facebook",
slug: "3223",
image: "/assets/images/serv/3223.png"
},
vkcom: {
count: 0,
popular: true,
price: 23,
id: 0,
service: "Вконтакте",
slug: "VKcom",
image: "/assets/images/serv/vkcom.png"
},
mailru: {
count: 540,
popular: true,
price: 2,
id: 2,
service: "MailRu",
slug: "MailRu",
image: "/assets/images/serv/mailru.png"
}
}

console.log(obj[3223]["count"])

for (key in obj) {
  console.log("Для key="+key+" count="+obj[key]["count"])
}

you can also use the forEach method

Object.keys(obj).forEach(function(key) {
  console.log(key, ':', this[key]["count"]);
}, obj);
