To repeat string, you can use Array() along with join().

Example

Following is the code −

<!DOCTYPE html>
<html lang="en">
<head>
   <meta charset="UTF-8">
   <meta name="viewport" content="width=device-width, initial-scale=1.0">
   <title>Document</title>
</head>
<link rel="stylesheet" href="//code.jquery.com/ui/1.12.1/themes/base/jquery-ui.css">
<script src="https://code.jquery.com/jquery-1.12.4.js"></script>
<script src="https://code.jquery.com/ui/1.12.1/jquery-ui.js"></script>
<script>
   String.prototype.counter = function (value) {
      return new Array(value + 1).join(this);
   }
   console.log("The repeat string
".counter(5));
</script>
</html>
