I want to mould a JSON object into the following required format:

Here is the,
Input data:

  let data = {
      phone_number: phone.phoneInputValue,
      platform: 'app',
      device_id: uniqueId,
      device_type: 'app',
      channel: 'sms',
    };

and this I want to generate as Output:

{"phone_number"=>"+919878249741",
     "platform"=>"app", "device_id"=>"123456", "device_type"=>"abcde",
     "channel"=>"sms"}

Achieved (the order is different) same I want to do for object keys currently its working on values only:

"channel=>"sms",device_id=>"a6335b3b84eaf86b",device_type=>"app",phone_number=>"+916555558998",platform=>"app"

Method used:

 const formattedString = JSON.stringify(data)
      .replace(/"([^"]+)":/g, '$1=>')
      .replace(/[{}]/g, '');

Any help is highly appreciated! Thanks
