Navigating through an object and dynamically inserting data using keys is a crucial skill to master

I've been delving into JavaScript objects lately.

1.

Units = [
    {
        "BedDetails": [
            {
                "Outpatient": 2,
                "ICU_Beds": 0,
                "NL_Beds": 2,
                "Extra": 9,
                "Ordinary": 3,
                "ADMIN": 6,
                "SVC_Areas": 3.2 // This is a different kind, not a type of bed
            }                  
        ]
    }, 
    {
        "BedDetails": [
            {
                "Outpatient": 4,
                "ICU_Beds": 2,                
                "Extra": 2,
                "Ordinary": 2,
                "ADMIN": 2,
                "SVC_Areas": 2.1 // This is a different kind, not a type of bed
            }
        ]
    }
]

Here are the three operations to perform:

Sum by types of beds.
If bed type > 0, then sum SVC_Areas as SVC_bedType.
Ratio of Bed type / SVC_bedtype.

For example:

Step 1 sums up bed types.
Step 2 includes:
If Outpatient > 0, then SVC_outpatient = 2.

If ICU > 0, then SVC_ICU = 0 (since ICU = 0).
Step 3 calculates the ratio: `(sum of bedtype) / SVC_bedtype` obtained in Step 1/Step 2.

This is what I've done so far:

Units.forEach(function (element) {               
    var Beds_Details = element.BedDetails[0];                   
    Sum_Outpatient += Beds_Details.Outpatient;
    Sum_ICUBeds += Beds_Details.ICU_Beds;                   
    Sum_Extra += Beds_Details.Extra;
    Sum_Ordinary += Beds_Details.Ordinary;
    Sum_ADMIN += Beds_Details.ADMIN;

    if (Beds_Details.Outpatient > 0) { (SVC_Outpatient += Beds_Details.SVC_Areas).toFixed(2); }
    if (Beds_Details.ICU_Beds > 0) { (SVC_ICUBeds += Beds_Details.SVC_Areas).toFixed(2); }                    
    if (Beds_Details.Extra > 0) { (SVC_Extra += Beds_Details.SVC_Areas).toFixed(2); }
    if (Beds_Details.Ordinary > 0) { (SVC_Ordinary += Beds_Details.SVC_Areas).toFixed(2); }
    if (Beds_Details.ADMIN > 0) { (SVC_ADMIN += Beds_Details.SVC_Areas).toFixed(2); }
});

if (SVC_Outpatient > 0) { 
   RatioModel_Outpatient = (Sum_Outpatient / SVC_Outpatient).toFixed(2); 
} else { 
         RatioModel_Outpatient = 0; 
};

// Check other conditions and calculate ratios here...

The code works fine, but I'm looking to optimize it by looping through the Bed_details keys. Can anyone help with this?

var output = {};
function calculatePropertySum(propertyName){
  var sum = 0;
  Units.forEach(function(obj){
      var item = obj.BedDetails["0"];
      sum =  sum + (item[propertyName]||0);
  });
  return sum;
};
function calculatePropertySVC(propertyName){
  var svc = 0;
  Units.forEach(function(obj){
    var item = obj.BedDetails["0"];
    if(item[propertyName]>0){
       svc = svc + (item.SVC_Areas||0);
    }
  });
  return parseFloat(svc.toFixed(2));
};

function getPropertyDetails(propertyName){
    var svc = calculatePropertySVC(propertyName);
    var sum = calculatePropertySum(propertyName);
    var ratio = svc === 0 ? 0: sum/svc;
    output["Sum_"+ propertyName] = sum;
    output["SVC_"+ propertyName] = svc;
    output["RatioModel_"+ propertyName] = parseFloat(ratio.toFixed(2));

}

var bedItem = Units[0].BedDetails[0];
for(var property in bedItem){
    if(property!=="SVC_Areas"){
            getPropertyDetails(property);
    }  
}
console.log(output);
