Using INTL to get the full week's days from today

Question

I'm trying to get the days of the week from the date of the specific day (e.g today is wednesday so I'd like to get today plus the 7 days after today) using the INTL. I have managed to get today's date but I'm unsure how to get the rest of the days.

              function daysForLocale(localeName = 'en', weekday = 'long') {
                const format = new Intl.DateTimeFormat(localeName, { weekday }).format;
                return [...Array(1).keys()]
                  .map((day) => format(new Date()));
              }
              console.log(daysForLocale());

output:

["Wednesday"]
["Wednesday"]
["Wednesday"]
["Wednesday"]
["Wednesday"]
["Wednesday"]
["Wednesday"]

Desired Output

["Thursday"]
["Friday"]
["Saturday"]
["Sunday"]
["Monday"]
["Tuesday"]
["Wednesday"]

`new Date()` always returns today. – AaronJ Aug 18 '21 at 15:54 — AaronJ, Aug 18 '21 at 15:54

Please use this code.

    function daysForLocale(localeName = 'en', weekday = 'long') {
        const format = new Intl.DateTimeFormat(localeName, { weekday }).format;
        const today = new Date();
        return [...Array(7).keys()]
          .map((val, index) => [format(new Date(today.getTime() + 3600 * 24 * 1000 * (index + 1)))]);
    }
    console.log(daysForLocale());

Thanks for your help this gets me all the days in one array. I'm looking to get each day in an array i.e ["Thursday"] ["Friday"] – user16698267 Aug 18 '21 at 16:07
I have updated this code. Please check again. – Kirill Savik Aug 18 '21 at 16:10
that worked thank you so much, I'll mark your answer as correct. For my own learning can you please walk me through what you did? – user16698267 Aug 18 '21 at 16:13
yes can you walk me through the changes you made any why it works? – user16698267 Aug 18 '21 at 16:32
With loop of index(0~6) I increased the date of today by (index + 1) day. So if today is Monday, the array is filled from Tuesday to Monday. – Kirill Savik Aug 18 '21 at 16:36
