How to use UpperCase filter in angular?

Is there a way I can do this with Angular Filter? For some reasons I'm not allowed to do it by Javascript ways, and creating additional files is not allowed as well

BTW, the purpose of the codes is to compare the users inputs whatever it is uppercase or lowercase, not just display the varName

<span data-ng-show="varName.toUpperCase() == 'YOURNAME'">
    Aswsome name !</span>

<span data-ng-hide="varName.toUpperCase() == 'YOURNAME'">
    {{varName}} is not my name.</span>

I have tried something like this but failed

<span data-ng-show="varName|uppercase == 'YOURNAME'">
    Aswsome name !</span>

Just put parentheses around the first 2 operands

<span ng-show="(varName | uppercase) == 'YOURNAME'">
    Aswsome name !</span>
</div>

try like this.

var editer = angular.module('editer', []);
function myCtrl($scope) {
$scope.varName = "yourname";
  
  $scope.toUpperCase = function(){
    return $scope.varName.toUpperCase();
  }
  
}
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.2.23/angular.min.js"></script>
<div ng-app="editer" ng-controller="myCtrl" class="container">
   
   <span data-ng-show="toUpperCase() == 'YOURNAME'">
    Aswsome name !</span>

<span data-ng-hide="toUpperCase() == 'YOURNAME'">
    {{varName}} is not my name.</span>

</div>

you have to use like this ....

   {{ uppercase_expression | uppercase}}

Example :

   <div ng-app>

    <p>
        <label>Enter your name (in lower case)</label>
        <input type="text" ng-model="yourname" />
    </p>

    <p> {{ yourname | uppercase }} </p>
</div>
