Create two identical object with different value javascript

Question

i have to create 2 identical object, one with value 'home' and other with value 'mailing' if the condition is true I send them both otherwise I send only 'home', what can I do?

it's correct to do that?

var arrayObj = []
var reqBodyAddress = {};
    
    reqBodyAddress.startDate = new GlideDateTime(current.u_data_inizio_contratto).getNumericValue();
    reqBodyAddress.addressType = function(){
    var objAddressType1 = {
            home:'home'
        }
    var objAddressType2 = {
            mailing:'mailing'
        }
        if(current.u_domicilio == true){
            reqBodyAddress.addressType = objAddressType1 + objAddressType2;
            }else{
            reqBodyAddress.addressType = objAddressType1;
        }
    };

arrayObj.push(reqBodyAddress);

var sReqBodyData = JSON.stringify(arrayObj);

Use Object.assign(target, ...sources) [read more] which copies multiple source objects into a target object, and then use a condition on the second object. similar to this:

let a = {foo:'foo'}
let b = {bar:'bar'}

let c = Object.assign(a, (false? b : null));
console.log(c) // {foo:"foo"}

let d = Object.assign(a, (true? b : null));
console.log(d) // {foo:"foo", bar:"bar"}

For your case, it would look like this:

reqBodyAddress.addressType = function(){
  var objAddressType1 = {
    home:'home'
  }
  
  var objAddressType2 = {
    mailing:'mailing'
  }
  
  reqBodyAddress.addressType = Object.assign(
    objAddressType1, // target
    (current.u_domicilio?  objAddressType2 : null) // source
  )
}

Note that this doesn't return a copy and will edit the target object. If you don't want to edit any objects when using this function, you can make your target an empty object {} and put all your objects as sources like this:

reqBodyAddress.addressType = function(){
  var objAddressType1 = {
    home:'home'
  }
  
  var objAddressType2 = {
    mailing:'mailing'
  }
  
  reqBodyAddress.addressType = Object.assign(
    {}, // empty target
    objAddressType1, // source 1
    (current.u_domicilio?  objAddressType2 : null) // source 2
  )
}
