function getMonthName(monthNumber) {
  const date = new Date();
  date.setMonth(monthNumber - 1);

  return date.toLocaleString([], { month: 'long' });
}

The current day of month will have an impact on the behavior of this method. Conceptually it will add the number of days given by the current day of the month to the 1st day of the new month specified as the parameter, to return the new date. For example, if the current value is 31st January 2016, calling setMonth with a value of 1 will return 2nd March 2016. This is because in 2016 February had 29 days.

    I encourage you to actually try using Java API to see how it works if you don’t think my example is illustrative enough. Meanwhile, the only insane thing here is you thinking that how an API works has anything to do with business stakeholders and requirements. This statement clearly illustrates that you don’t understand how to translate business requirements into code and perhaps should spend some time learning how to do that instead of trolling here.
