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 love js. But the date object has always been a total pain. Moment.js is a good package to deal with it, but yeah, it's currently deprecated, but it would be nice if it or something like it became part of ECMAScript.

      I have no idea why it hasn't yet, except that it might be that js needs to work for everyone, not just the us. So time is not standard.

        The date API is like the original rip of the Java date API. Barely changed, and totally backwards compatible nonsense.

        Temporal is the new JavaScript/ECMAScript date API.
        It's stage 3, and likely stable (just a few kinks being worked out). So you could polyfill it for production.

          Speaking of Java RipS. How annoying is it the JS has left Java in the dust as far as looser standards?
