I need to group elements by some properties of the object of an array. I don't want to use custom pipe for that. Is there any way to implement group by.

Sample Array:

[  
   {  
      "id":1,
      "date": "2018-02-01T19:24:05.524+05:30",
      "client":{  
         "id":1
      },
      "process":{  
         "id":1,
         "date":"02-01-2018 11:54:05"
      }
   },
   {  
      "id":2,
      "date": "2018-02-01T17:35:05.524+05:30",
      "client":{  
         "id":2
      },
      "process":{  
         "id":2,
         "date":"02-01-2018 11:54:05"
      }
   },
]

I want to group array by date, client Id and process date.

I am trying to use lodash group-by. For client Id It is working fine but for the other dates I want to group elements by date only . I don't want to include time in that. Is there any way to exclude time in group-by?

Hope someone can help

what is the output object will look like? – Aravind Feb 01 '18 at 12:15
do you need to group the array or just list grouped? if you want to show it grouped, you can try `angular` `groupBy`: https://stackoverflow.com/a/37717769/4730201 – Ricardo Pontual Feb 01 '18 at 12:16
@Aravind In outout object all the elements related to all the clients would be listed together.. like 1 object for client Id 1 and It should display all the records where client ID is 1 same for other client Ids – Aakriti.G Feb 01 '18 at 12:19
@RicardoPontual I dont want to use pipes as I need to process some data in my component – Aakriti.G Feb 01 '18 at 12:20
have a look at the lodash [**groupBy**](https://lodash.com/docs/4.17.4#groupBy) – Aravind Feb 01 '18 at 12:23
have you read this: https://stackoverflow.com/questions/40774697/how-to-group-an-array-of-objects-by-key – Ricardo Pontual Feb 01 '18 at 12:25
Ok I will try lodash groupBy .. – Aakriti.G Feb 01 '18 at 12:28
