Test sample:

<script type="text/javascript">
	
	class myDate extends Date {
		
		constructor() {
			super();
		}

		
		getFormattedDate() {
			var months = ['Jan','Feb','Mar','Apr','May','Jun','Jul','Aug','Sep','Oct','Nov','Dec'];
			return this.getDate() + "-" + months[this.getMonth()] + "-" + this.getFullYear();
		}
	}

	

function foo(){
		return "foo ";
	}

	function bar(){
		return "bar ";
	}

	function test() {
		var d = new myDate();
  s = ""
		s = d.getFormattedDate();
		for (var i = 0; i < 10; i++){
			if (i%2 === 0){
				s += foo();
			} else {
				s += bar();
			}
		}
		return s;
	}	
</script>
