array how can I start a loop from the middle and make it end at the element before the start?-CodePudding

Newbie here! I want to start the loop based on today (ex:"Thursday") and I want to make it stop on "Wednesday"...is that possible? Any help is appreciate! thanks

    let days = [
      "Sunday",
      "Monday",
      "Tuesday",
      "Wednesday",
      "Thursday",
      "Friday",
      "Saturday",
    ];
    let date = new Date();
    let today = date.getDay();
    let result = [];
    

    for (let i = today; i < days.length; i  ) {
      result.push(days[i]);
    }

    return result[index];
  };```

For simplicity, you could loop from today to days.length, then again from 0 to today.

let days = [
      "Sunday",
      "Monday",
      "Tuesday",
      "Wednesday",
      "Thursday",
      "Friday",
      "Saturday",
    ];
    let date = new Date();
    let today = date.getDay();
    let result = [];
    

    for (let i = today; i < days.length; i  ) {
      result.push(days[i]);
    }
    for (let i = 0; i < today; i  ) {
      result.push(days[i]);
    }

    console.log(result);
