Create a dynamic nested object from array of properties

Question

This sounds like a simple task, but I can\'t quite figure it out: I have an array :

var array = [\'opt1\',\'sub1\',\'subsub1\',\'subsubsub1\']

You can use the following Function

function arr2nestedObject(myArray){
 var cp_myArray = myArray;
 var lastobj = {};
 while(cp_myArray.length>0){
    newobj = {};
    var prop = cp_myArray.pop();
    newobj[prop] = lastobj;
    lastobj = newobj;
 }
 return lastobj;
}

The following code:

var myArray = ["personal-information", "address", "street",'Great-Success'];
console.log(JSON.stringify(arr2nestedObject(myArray),undefined,2));

Would Produce the Following Output:

{
  "personal-information": {
   "address": {
    "street": {
     "Great-Success": {}
     }
    }
  }
}

Please let me know if that was what you meant.

Kind Regards.
