I have two variables of type Properties
And I want to merge together with another third variable
This is for example the two variables

var firstProperty = new Properties(); 
var dateAndTime = "11111";
var vmName = "vm_First_Property";                  

var value = {};                      
value[vmName] = {                    
    "Company": 'google',              
    "site": 'USA',                 
    "Year": 1550            
};                                              
firstProperty.put(dateAndTime, value);  


// Initialize the second object with another property 
var secondProperties = new Properties(); 
var dateAndTime = "22222";
var vmName = "vm_second_Property";                  

var value = {};                      
value[vmName] = {                    
    "Spaceavailable": 304,              
    "UsedSpace": 85,                
    "DataReduction": 1.3            
};                                              
secondProperties.put(dateAndTime, value);

I Try to output all variables
firstProperty, secondProperties and merge Properties
