Date editing : remove the zero prefix from the month

Question

The following code returns me next Friday date. I have added an IF in order to remove the first 0 from the month variable,since I need it without the 0 prefix. But it doesn't work. What is the error I'm doing ?

<script type="text/javascript">

function nextWeekdayDate(date, day_in_week) {
var ret = new Date(date||new Date());
ret.setDate(ret.getDate() + (day_in_week - 1 - ret.getDay() + 7) % 7 + 1);
return ret;
}

var date = new Date();
console.log(nextWeekdayDate(date, 5));

  $(document).ready(function() {
  $('#button').click(function(e) {  
      var date = nextWeekdayDate(null, 5);
      var [yyyy, mm, dd] = date.toISOString().split('T')[0].split('-');

      if ([mm hasPrefix:@"0"] && [string length] > 1) {
  mm = [string substringFromIndex:1];
}

      window.open(`https://www.mydinamiclink.com/`+mm);

                      });

      });


</script>

thanks for your help

Note that this gets the UTC date, not the local date, which will be different near midnight for the period of the local daylight saving offset.

Turn the month number into a number and back into a string:

 var [yyyy, mm, dd] = (new Date('2020-05-01')).toISOString().split('T')[0].split('-');
 
 console.log('before leading 0 removal:', mm);
 
 mm = parseInt(mm, 10).toString();
 
 console.log('after leading 0 removal:', mm);
