The Elvis operator (?:) is a small but elegant feature added in Splendor. I am going to show you how it shortens your conditional code and  makes it look simpler. But before I get into the details, here is the list of language features added in ColdFusion Splendor.

• Script support for tags
• Member functions for CF data type/data structure
• Improved JSON serialization
• Easy to use CF functions for Query tag
• Elvis operator (?:)
• Promoting built-in CF function to first class 
• Miscellaneous new functions: QueryGetRow, ListEach and others. 

<cfscript>
   if(isdefined('username')){
       displayName = username;
   }
   else {
    displayName = "anonymous";
   }
</cfscript>

With Elvis operator

   displayName = username ?: "anonymous";

The support for Elvis operator has been provided for function calls and expressions too. Some of the expression cases are: 

 securityNumber = securityStruct[‘Joe’] ?: -1;  // Retrieving from a struct
 colourCode = colourArray[index] ?: "black";   // Retrieving from an array
 employeeName = getEmployeeName(ID) ?: “Joe”;  // A function call
