I want to code something like this where you can see the weeks and switch between them. At the moment I wrote these days in HTML, so it is not dynamic. I am new to this, so I don't know what JS library can do something like this. I managed to find something that gives you the current week. However, I don't think this is the right approach.

var  week = {
  period: null,

  load: function () {
    var d = new Date(); // today, now
     week.period = d.setDate(d.getDate() + ((7 - d.getDay()) % 7 + 1) % 7);
    document.getElementById("date").innerHTML = dayjs( week.period).format("DD/MMM/YYYY");
  },
  };

 week.load();

 <h1 id="date"></h1>

This way I get the next Monday. How would you go from here? I want to first get the weeks done. I have the fetch under control, as I have JSON data.
