“如何在JavaScript中使用多个变量的嵌套switch语句？

可以使用嵌套的switch语句来比较多个变量的不同组合。以下是一个示例，其中有两个变量：day和meal：

let day = "Monday";
let meal = "dinner";
switch (day) {
  case "Monday":
  case "Tuesday":
  case "Wednesday":
  case "Thursday":
  case "Friday":
    switch (meal) {
      case "breakfast":
        console.log("Cereal and milk");
        break;
      case "lunch":
        console.log("Soup and sandwich");
        break;
      case "dinner":
        console.log("Steak and potatoes");
        break;
      default:
        console.log("Invalid meal time");
        break;
    break;
  case "Saturday":
    console.log("Brunch");
    break;
  case "Sunday":
    console.log("Pancakes");
    break;
  default:
    console.log("Invalid day");
    break;
