Transform data in array

I need to transform data from first format to second for my ui library. But I can't completely understand how I should do this. I need to add arrays "data" each id

My data:

[
{id: 'Battery charging', time: '2021-0903T14:10:00Z', value: 3890.019022727273, table: 0} 
{id: 'Battery charging', time: '2021-09-03T14:15:00Z', value: 3594.3097145454544, table: 0}
{id: 'Battery charging', time: '2021-09-03T14:20:00Z', value: 4069.6454163636363, table: 0} 
{id: 'Battery charging', time: '2021-09-03T14:25:00Z', value: 4090.7089309090907, table: 0} 
{id: 'Battery charging', time: '2021-09-03T14:30:00Z', value: 3530.3841, table: 0} 
{id: 'Battery charging', time: '2021-09-03T14:35:00Z', value: 4154.7032509090905, table: 0}
 {id: 'Battery charging', time: '2021-09-03T14:40:00Z', value: 4752.12578, table: 0}
{id: 'Battery charging', time: '2021-09-03T14:45:00Z', value: 5906.133650000001, table: 0}
 {id: 'Battery charging', time: '2021-09-03T14:50:00Z', value: 4148.342200000001, table: 0} 
{id: 'Battery discharging', time: '2021-09-03T14:10:00Z', value: 0, table: 1} 
{id: 'Battery discharging', time: '2021-09-03T14:15:00Z', value: 0, table: 1} 
{id: 'Battery discharging', time: '2021-09-03T14:20:00Z', value: 0, table: 1} 
{id: 'Battery discharging', time: '2021-09-03T14:25:00Z', value: 0, table: 1} 
{id: 'Battery discharging', time: '2021-09-03T14:30:00Z', value: 0, table: 1} 
{id: 'Battery discharging', time: '2021-09-03T14:35:00Z', value: 0, table: 1} 
{id: 'Battery discharging', time: '2021-09-03T14:40:00Z', value: 0, table: 1} 
{id: 'Battery discharging', time: '2021-09-03T14:45:00Z', value: 0, table: 1} 
{id: 'Battery discharging', time: '2021-09-03T14:50:00Z', value: 45.93099, table: 1} 
]

Need to transform to this:

[
{id: 'Battery charging', 
data: [
{time: '2021-09-03T14:10:00Z', value: 3890.019022727273} 
{time: '2021-09-03T14:15:00Z', value: 3594.3097145454544}
 {time: '2021-09-03T14:20:00Z', value: 4069.6454163636363} 
{time: '2021-09-03T14:25:00Z', value: 4090.7089309090907} 
{time: '2021-09-03T14:30:00Z', value: 3530.3841} 
{time: '2021-09-03T14:35:00Z', value: 4154.7032509090905} 
{time: '2021-09-03T14:40:00Z', value: 4752.12578}
{time: '2021-09-03T14:45:00Z', value: 5906.133650000001}
 {time: '2021-09-03T14:50:00Z', value: 4148.342200000001}
] 
{id: 'Battery discharging',
data: [
{time: '2021-09-03T14:10:00Z', value: 0}
{ time: '2021-09-03T14:15:00Z', value: 0}
{ time: '2021-09-03T14:20:00Z', value: 0}
 {time: '2021-09-03T14:25:00Z', value: 0}
 {time: '2021-09-03T14:30:00Z', value: 0}
{ time: '2021-09-03T14:35:00Z', value: 0}
{ time: '2021-09-03T14:40:00Z', value: 0}
{ time: '2021-09-03T14:45:00Z', value: 0}

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
