Sorry for this. Ok, in first fetch i get list of friends. In second i tried get one picture for every friend, and build new array whit adding new lines (first_name and photo_200). But it looks weird. Program shows some of friend (random count) and in random order O_O. And frnd variable work only in fetch, when i tried use it in other func i get ‘undefined’. Very sorry for my english, but this problem will kill me soon 
var Observable = require('FuseJS/Observable');
var sphoto = Observable();
var token = Observable("");
var arr = Observable();
var frnd = Observable();
var friends = Observable();
var k = 0;
this.Parameter.onValueChanged(function(args) {
token.value = args;
getAllSave();
});
function getAllSave() {
var url = "https://api.vk.com/method/friends.get?";
url += "access_token=" + token.value + "&fields=photo_200&order=hints";
fetch(url) //i get list of friends
.then(function(res) {
return res.json();
})
.then(function(resJson) {
frnd.value = resJson;
console.log("frnd.value = " + JSON.stringify(frnd.value));
url = "https://api.vk.com/method/photos.get?";
frnd.value.response.forEach(function(r) {
url += "access_token=" + token.value + "&owner_id=" + r.uid + "&album_id=saved&rev=1&count=10&extended=1";
fetch(url)
.then(function(res) {
return res.json();
})
.then(function(resJson) {
k++;
console.log("it is " + k + " iteration, name is " + r.first_name)
for (var j = 0; j < 1; j++) {
resJson.response[j].first_name = r.first_name;
resJson.response[j].photo_200 = r.photo_200;
friends.add(resJson.response[j]);
}
})
.catch(function(err) {
console.log("err" + err);
})

})
})
}
module.exports = {
