Get localized month name using native JS

问题

It's possible to do this to get the localized full month name using native javascript.

var objDate = new Date("10/11/2009"),
    locale = "en-us",
    month = objDate.toLocaleString(locale, { month: "long" });

But this only gets the month number for a given date. I'd simply like to get the month name corresponding to a month number. For example, if I do getMonth(2) it would return February. How can I implement getMonth using native javascript(no libraries like moment)?

You are already close:

var getMonth = function(idx) {

  var objDate = new Date();
  objDate.setDate(1);
  objDate.setMonth(idx-1);

  var locale = "en-us",
      month = objDate.toLocaleString(locale, { month: "long" });

    return month;
}

console.log(getMonth(1));
console.log(getMonth(12));
