Question

array of objects from database
        [
          {
            campaign_definition_id: '125',
            campaign_activity_id: '90',
            member_id: 127863,
            template_name: null,
            template_id: '8498'
          },
          {
            campaign_definition_id: '125',
            campaign_activity_id: '90',
            member_id: 130349,
            template_name: null,
            template_id: '8498'
          },
          {
            campaign_definition_id: '125',
            campaign_activity_id: '90',
            member_id: 172867,
            template_name: null,
            template_id: '8498'
          },
            {
            campaign_definition_id: '125',
            campaign_activity_id: '91',
            member_id: 127863,
            template_name: null,
            template_id: '9093'
          },
          {
            campaign_definition_id: '125',
            campaign_activity_id: '91',
            member_id: 130349,
            template_name: null,
            template_id: '9093'
          },
          {
            campaign_definition_id: '125',
            campaign_activity_id: '91',
            member_id: 172867,
            template_name: null,
            template_id: '9093'
          }
        ]

Expected Result:

[
 {
    campaign_definition_id: '125',
    campaign_activity_id: '90',
    member_id: [127863,130349,172867],
    template_name: null,
    template_id: '8498'
 
 }
 {
 campaign_definition_id: '125',
    campaign_activity_id: '91',
    member_id: [127863,130349,172867],
    template_name: null,
    template_id: '9093'
  }
]

let result = data.reduce((acc, s) => {
    if (acc[s.campaign_activity_id]) {
        if (typeof acc[s.campaign_activity_id].member_id === 'number') {
            acc[s.campaign_activity_id].member_id = [
              acc[s.campaign_activity_id].member_id, s.member_id
            ];
        } else if (Array.isArray(acc[s.campaign_activity_id].member_id)) {
          acc[s.campaign_activity_id].member_id = [
            ...acc[s.campaign_activity_id].member_id,
            s.member_id,
          ];
        }
    } else {
        acc[s.campaign_activity_id] = s;
    }
    return acc;
}, {})

console.log(Object.values(result));

In array of object, we need take same related id and pushing in one object
