Sorting json objects by specific value

问题

I am sending data that I have already sorted by number of counts, from my controller in Laravel to my script file. Json data that I am sending looks like this:

{"5":{"title":"Coop post title","summary":"dbsbsb","count":5},
 "7":{"title":"Example article","summary":"fdsbdfsbsffd","count":5},
 "6":{"title":"Coop's post","summary":"sdbadbb","count":3},
 "0":{"title":"sdvsdv","summary":"dsvsdv","count":2},
 "4":{"title":"sdvsdv","summary":"dsvsdv","count":1}}

But when I parse json data like this in my script file data gets random again:

var cleanData = $.parseJSON(data);
        console.log(cleanData);

And then I get in console data that looks like this:

Object {0: Object, 4: Object, 5: Object, 6: Object, 7: Object}
  0:Object
    count:2
    summary:"dsvsdv"
    title:"sdvsdv"
    __proto__:Object
  4:Object
    count:1
    summary: "dsvsdv"
    title: "sdvsdv"
    __proto__:Object
  5:Object
    count:5
    summary: "dbsbsb"
    title: "Coop post title"
    __proto__: Object
  6:Object
    count:3
    summary: "sdbadbb"
    title: "Coop's post"
    __proto__: Object
  7:Object
    count:5
    summary: "fdsbdfsbsffd"
    title: "Example article"
    __proto__: Object

You can sort using lodash#sortBy:

_.sortBy(collection, [iteratees=[_.identity]])

Creates an array of elements, sorted in ascending order by the results of running each element in a collection (Array|Object) thru each iteratee. This method performs a stable sort, that is, it preserves the original sort order of equal elements. The iteratees are invoked with one argument: (value).

var cleanData = {"5":{"title":"Coop post title","summary":"dbsbsb","count":5},"7":{"title":"Example article","summary":"fdsbdfsbsffd","count":5},"6":{"title":"Coop's post","summary":"sdbadbb","count":3}, "0":{"title":"sdvsdv","summary":"dsvsdv","count":2}, "4":{"title":"sdvsdv","summary":"dsvsdv","count":1}};

cleanData = _.sortBy(cleanData, ['count']);
console.log(cleanData);
