Uncaught TypeError: angular.lowercase is not a function

this error in my angularjs application, and entire application is not running. This

Answer 1

I am using AngularJS v1.7.5 . In my controller, I have used below code to convert a string into lowercase:

function myCtrl($scope, $filter)
{
    var sampleText = "THIS IS TEST";
    var test = $filter('lowercase')(sampleText);
}

Inject $filter in the controller and use the same to convert to lowercase.
