How to get month name for a given year and week in Javascript

Issue

I have 2 form fields in HTML namely Year and Week.

Once the user selects a Year and a week from the dropdowns, I want to display the month Name for the selected year and week.

Can anyone help me to get month name based on year and iso week numbers.

For example: If I selected year as 2022 and week no as 16, then the expected output is April as a month name.

This shoud be a function that returns the month name for a given year and week.

Below is my sampke code.

getMonthName() {
    const year  =  2022;
    const week  = 16;
    console.log(month);
  }

Solution

The following will display the month name (short form) for the given ISO week number and year.

function getMonthName(week, year) {
let d =new Date(year,0,1+(week-1)*7);
d.getUTCDay()<5?d.setUTCDate(d.getUTCDate()-d.getUTCDay()+1):d.setUTCDate(d.getUTCDate()+8-d.getUTCDay());
return (""+d).split(" ")[1];
}

console.log(getMonthName(1,2022));
console.log(getMonthName(11,2022));
console.log(getMonthName(16,2022));
