JS switch - default keyword

let text;
switch (new Date().getDay()) {
  default:
    text = "Are you looking forward to the Weekend?";
    break;
  case 6:
    text = "Today is Saturday";
    break;
  case 0:
    text = "Today is Sunday";
}
document.getElementById("demo").innerHTML = text;

If default is not the last case in the switch block, remember to end the default case with a break.
