There is really no need of for-loop, you can easily find that country with the find method:

    res.locals.contrycode = function(code1) { //helper function

         var selectedCountry = result.find(function(country) {
           return country.phoneCode === code1;
         });

         if (selectedCountry) { // country found with this code
           return selectedCountry.name;
         } else {
           return "whatever you want"
         }

      }

Please update your code.

I hope it will help.
