Ok So For Example let's say this is My Object.

const myObj = {
   cf_retryAttempts:0,
   cf_amount:1,
   cf_event:"SUBSCRIPTION_NEW_PAYMENT",
   cf_eventTime:"2022-01-10 10:03:50",
   cf_paymentId:1,
   cf_referenceId:2,
   cf_subReferenceId:3,
}

If I use JSON.stringify(myObj) it returns something like {"cf_retryAttempts":"0"...} But I don't want that what I want is a complete string without any doubleQuotes, commas or colon separators between key value. so what I'm expecting is something like:

const string = cf_amount1cf_eventSUBSCRIPTION_NEW_PAYMENTcf_eventTime2022-01-10 10:51:02cf_paymentId1cf_referenceId2cf_retryAttempts0cf_subReferenceId3

If you want to understand more please check the docs as to understand what I'm trying to achieve.

You can iterate all its keys and values, also recursively if you encounter an object.

const myObj = {
  cf_retryAttempts: 0,
  cf_amount: 1,
  cf_event: "SUBSCRIPTION_NEW_PAYMENT",
  cf_eventTime: "2022-01-10 10:03:50",
  cf_paymentId: 1,
  cf_referenceId: 2,
  cf_subReferenceId: 3,
  cf_inner: {
    'this': 'that'
  }
}

function iterate(obj) {
  var result = ""
  Object.entries(obj).forEach(function([key, value]) {
    if (typeof value === 'object' && value !== null) {
      result  = (key   iterate(value))
    } else {
      result  = (key   value)
    }
  })
  return result;
}
console.log(iterate(myObj))

simply ?
cf_ elements are sorted.

const myObj = 
  { cf_retryAttempts  : 0
  , cf_amount         : 1
  , cf_event          : 'SUBSCRIPTION_NEW_PAYMENT'
  , cf_eventTime      : '2022-01-10 10:03:50'
  , cf_paymentId      : 1
  , cf_referenceId    : 2
  , cf_subReferenceId : 3
  , signature         : 'tT9pXZkT2LuDzXacYDUaur7EX3dJgNKcITHQng44tns='
  } 

function objStr( {signature, ...cf_x })
  {
  return Object.entries(cf_x)
    .sort((a,b)=>a[0].localeCompare(b[0]))
    .reduce((r,[e,k])=> r e k,'')
  }
 
console.log( objStr(myObj) )
