Function title var

Question

I have written a code that finds two strings and in return it should tell me if these two strings are existing:

 function searchTwoString(data, str1, str2) {

   var strX = str1 + " " + strValueX + "\r\n";
   var strY = str2 + " " + strValueY;
   var strValueX;
   var strValueY;

   for (var i = 0; i < data.length; i++) {
     if (data[i] === str1) {
       var strValueX = " exist";
       continue;

     } else if (data[i] === str2) {
       var strValueY = " exist";
       break;
     } 
   }

   return strX + strY;

 }

Achieved result:

str1 undefined

str2 undefined

Expected result:

str1 exist

str2 exist

it tells me my strvalueX & strvalueY are undefined isn't it i have already gave the values in the if statement?

thanks to those who will help out

Here is an answer to your question with comment.

Hope you understand what I'm talking about.

function searchTwoString(data, str1, str2) {

   var strX;// = str1 + " " + strValueX + "\r\n";
   var strY;// = str2 + " " + strValueY;
   var strValueX;
   var strValueY;

   for (var i = 0; i < data.length; i++) {
       if (data[i] === str1) {
           // var strValueX = " exist";
           // do not define again
           strValueX = " exist";
           continue;

       } else if (data[i] === str2) {
           // var strValueY = " exist";
           // do not define again
           strValueY = " exist";
           break;
       }
   }
   // define the value here after strValueX and strValueY is set
   strX = str1 + " " + strValueX + "\r\n";
   strY = str2 + " " + strValueY;

   return strX + strY;

}
