Tips for using ng-repeat with a hardcoded value instead of an array

Is there a way to manually run the ng-repeat function a specific number of times without passing an array parameter? I attempted to hardcode the number in the ng-repeat attribute, but it didn't work as expected.

<h1 ng-repeat="x in 20">{{sumofTwendy(($index}})</h1>

My next approach was to create a dummy array in the controller with a length of 20 and use that array in the ng-repeat.

$scope.data=[];
$scope.data.length=20;
<h1 ng-repeat="x in data">{{sumofTwendy(($index}})</h1>

However, this method also did not work as intended.

Is there a way to execute ng-repeat a specific number of times without passing array values? I'm looking for a solution in either Angular 1 or Angular 2.

If you have a solution, please let me know.

A new array can be generated by passing a variable to a function,

var myApp=angular.module('myApp',[]);

myApp.controller('thecontroller',function($scope){
$scope.getNumber = function(num) {
    return new Array(num);   
}
});
