"left join" two arrays with a twist.

Posted on by 11

I have two outputs from a parse JSON I need to join.  I'm having a difficult time because the numbers in set one are not known and will change every run.  The numbers in set two will always be exactly 1:1 of set one.  I need to "left join" the two so that I end up with something like the final set below.  I know how to do it if the number in set one doesn't change... but I'm having a hard time wrapping my mind on how to do this when the "field name" will be different.  I thought of a apply to each of the first set with a filter of the second set  but I dont know how to address the first item in the set without knowing its "name" so to speak.    Please help if you can.

 

Set 1.

 

{
  "2778101": "29",
  "2778111": "23.5",
  "2778115": "24"
}
 
Set 2
{
"2778101": {
"id": 2778101,
"first_name": "John",
"last_name": "Smith",
},
"2778111": {
"id": 2778111,
"first_name": "Jason",
"last_name": "Smith",
},
"2778115": {
"id": 2778115,
"first_name": "Kyle",
"last_name": "Smith",
}

}
 
Desired Output
{
"John Smith": "29",
"Jason Smith": "23.5",
"Kyle Smith": "24"
}
