How can i generate each time the same secuence?

i have this function to sort randomly but now i need the same secuence each time

function shuffle(array) {
  let currentIndex = array.length,  randomIndex;

  while (currentIndex != 0) {

    randomIndex = Math.floor(Math.random() * currentIndex);
    currentIndex--;

    [array[currentIndex], array[randomIndex]] = [
      array[randomIndex], array[currentIndex]];
  }

  return array;
}

var arr = [2, 11, 37, 42];
shuffle(arr);
console.log(arr);
