How I can group items by month, by value in "created_date"?
Need get items just one month

Answer 1

So if I understand you correctly you want to group your items by the month value which is stored in the property created_date. The following code will do that for you.
var items = [
{
"id": 1766013,
"created_date": "2019-01-28 12:54:23",
"amount": 10000,
"type": "payin",
"status": "done",
"method": "m_visamc"
},
{
"id": 1766012,
"created_date": "2019-03-28 12:54:08",
"amount": 300000,
"type": "payin",
"status": "error",
"method": "m_visamc"
},
{
"id": 1766011,
"created_date": "2019-02-28 12:53:31",
"amount": 6000,
"type": "payin",
"status": "done",
"method": "m_visamc"
},
{
"id": 1766012,
"created_date": "2019-02-26 12:53:36",
"amount": 6000,
"type": "payin",
"status": "done",
"method": "m_visamc"
}];
var groupByCreatedDateMonth = array =>
array.reduce((objectsByKeyValue, obj) => {
var dateString = obj.created_date;
var date = new Date(dateString);
var value = date.getMonth();
objectsByKeyValue[value] = (objectsByKeyValue[value] || []).concat(obj);
return objectsByKeyValue;
}, {});
var result = groupByCreatedDateMonth(items);
console.log(result);
