Remove the last part of the returned string using textToPrint.slice(0,-1)

function currentLine(katzDeliLine) {
   if (katzDeliLine.length > 0) {
   var textToPrint = "The line is currently: "  

   for (var crrLine = 0;  crrLine < katzDeliLine.length; crrLine++) {
     textToPrint = textToPrint + (crrLine + 1)+". " +katzDeliLine[crrLine]+","
   }

   return textToPrint.slice(0,-1);
   } 
   else {
      return "The line is empty"
   }
}

 var lineofpeople = ["katrina", "kevin", "vincent"]
 console.log(currentLine(lineofpeople));
