Answer 1

   String.format = function () {
      // The string containing the format items (e.g. "{0}")
      // will and always has to be the first argument.
      var theString = arguments[0];

      // start with the second argument (i = 1)
      for (var i = 1; i < arguments.length; i++) {
          // "gm" = RegEx options for Global search (more than one instance)
          // and for Multiline search
          var regEx = new RegExp("\\{" + (i - 1) + "\\}", "gm");
          theString = theString.replace(regEx, arguments[i]);
      }

      return theString;
  }

  $http.get(String.format("/Student/GetStudentById?studentId={0}&collegeId={1}", $scope.studentId , $scope.collegeId))
      .then(function (result) {
      });

Answer 2

Try this,

String.format = function(str) {
   var args = arguments;
   return str.replace(/{[0-9]}/g, (matched) => args[parseInt(matched.replace(/[{}]/g, ''))+1]);
};

string.format("/Student/GetStudentById/{0}/collegeId/{1}",studentId,collegeId)
