Transform data in array of objects

I need to transform data from server format to format for my UI library. But I can't completely understand how I should do this.

Name in new object is a field in object from server except "time" And add "time" value for each fields Need to transform this:

[
 {
 battery_charge: 0 
 battery_discharge: 0 
 consumption: 404  
 grid_backflow: 0  
 grid_consumption: 3  
 pv_generation: -7  
 time: "2019年02月25日T00:00:00+00:00" 
 }
 {
 battery_charge: 0  
 battery_discharge: 0  
 consumption: 404  
 grid_backflow: 0  
 grid_consumption: 3  
 pv_generation: -7  
 time: "2019年02月25日T10:00:00+00:00" 
 }
]

to this:

[
 {
 name: ‘Battery Charge’
 data: [
 { time: '2019-02-25T10:00:00+00:00', value: 3 }
 { time: '2019-02-25T10:00:00+00:00', value: 3 }
 ]
 }
 {
 name: ‘Battery discharge’
 data: [
 { time: '2019-02-25T10:00:00+00:00', value: 3 }
 { time: '2019-02-25T10:00:00+00:00', value: 3 }
 ]
 }
 {
 name: ‘Consumption’
 data: [
 { time: '2019-02-25T10:00:00+00:00', value: 3 }
 { time: '2019-02-25T10:00:00+00:00', value: 3 }
 ]
 }
 {
 name: ‘Grid backflow’
 data: [
 { time: '2019-02-25T10:00:00+00:00', value: 3 }
 { time: '2019-02-25T10:00:00+00:00', value: 3 }
 ]
 }
 {
 name: ‘Grid consumption’
 data: [
 { time: '2019-02-25T10:00:00+00:00', value: 3 }
 { time: '2019-02-25T10:00:00+00:00', value: 3 }
 ]
 }
 {
 name: ‘Pv generation’
 data: [
 { time: '2019-02-25T10:00:00+00:00', value: 3 }
 { time: '2019-02-25T10:00:00+00:00', value: 3 }
 ]
 }
]

var keys = {
 battery_charge: "Battery Charge",
 battery_discharge: "Battery discharge",
 consumption: "Consumption",
 grid_backflow: "Grid backflow",
 grid_consumption: "Grid consumption",
 pv_generation: "Pv generation",
 };

 var data = [
 {
 battery_charge: 0,
 battery_discharge: 0,
 consumption: 404,
 grid_backflow: 0,
 grid_consumption: 3,
 pv_generation: -7,
 time: "2019年02月25日T00:00:00+00:00",
 },
 {
 battery_charge: 0,
 battery_discharge: 0,
 consumption: 404,
 grid_backflow: 0,
 grid_consumption: 3,
 pv_generation: -7,
 time: "2019年02月25日T10:00:00+00:00",
 },
 ];

 var formatted = [];

 data.map((k) => {
 Object.keys(keys).map((x) => {
 if (!formatted.some((f) => f.key == x)) {
 formatted.push({

 key: x,
 data: [],
 });
 }

 if (
 formatted.some(
 (y) => y.data.some((f) => f.time == k.time) && y.key == x
 )
 ) {
 var index = formatted.findIndex(
 (y) => y.data.some((f) => f.time == k.time) && y.key == x
 );
 var dataIndex = formatted[index].data.findIndex(
 (f) => f.time == k.time
 );
 formatted[index].data[dataIndex].value += k[x];
 } else {
 var index = formatted.findIndex((k) => k.key == x);
 formatted[index].data.push({ value: k[x], time: k.time });
 }
 });
 });

 console.log(formatted);

How to Tag

A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.

complete the sentence: my question is about...
use tags that describe things or concepts that are essential, not incidental to your question
favor using existing popular tags
read the descriptions that appear below the tag

If your question is primarily about a topic for which you can't find a tag:

combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
