Compare Two Json object's value and Find the Difference in Using Java Script

Question

We have two JSON data which we would like to compare and get the difference between the values of two Keys , Count in First JSON data compared with AVG_X in JSON data .

First JSON-

var myObject=[
  {
    "Customer": "A",
    "Count": 47
  },
  {
    "Customer": "B",
    "Count": 5
  },
  {
    "Customer": "C",
    "Count": 1
  }
]

Second JSON-

var myobject1=[
  {
    "Customer": "A",
    "AVG_X": 20
  },
  {
    "Customer": "B",
    "AVG_X": 4
  },
  {
    "Customer": "C",
    "AVG_X": 0
  },
  {
    "Customer": "D",
    "AVG_X": 3
  }
]

Also the data size of First JSON is the length of the loop in which we need to iterate .

For that I am using this below function -

var key, count = 0;
  for(key in myObject) {
  if(myObject.hasOwnProperty(key)) {
    count++;
  }
}

Now to compare the values the of Count vs AVG_X and get the difference between these two for each Customer and save it in new JSON .

I am thinking around the below code but I am not 100% sure -

// find keys 
keyObj1 = Object.keys(myObject); 
keyObj2 = Object.keys(myObject1); 


// find values 
valueObj1 = Object.values(myObject); 
valueObj2 = Object.values(myObject1); 
 
// now compare their keys and values  
for(var i=0; i<count; i++) { 
  if(keyObj1[i] == keyObj2[i] && valueObj1[i] == valueObj2[i]) { 
     console.log(valueObj2[i]);  
    } 
   else { 
            // it prints keys have different values 
            console.log('myObject1 value: '+ valueObj1[i] + '\nmyObject2 value: '+ valueObj2[i] +'\n'); 
            } 
        }
        
};      

Expected Output Should be something like below -

{
"Customer": "A", 
"Diff": 27
},
{
"Customer": "B", 
"Diff": 1 
},
"Customer": "C", 
"Diff": 1 
}

Help would be much appreciated !!
