switch 块中的 If 语句 javascript

Question

是否可以在 Javascript 的 switch 块中使用来自 switch 块的响应的 if/else 语句？以下是我这样做的尝试。这是一个 CodeAcademy 项目，您必须在其中使用开关块和条件语句编写自己的冒险故事。

var user = prompt("You awake; dazed, blurred and lost. What do you do?").toLowerCase()
var day = 0;

switch (user) {
    case "look at the time":
        console.log("Good start, how long was I out for?");
        if (
        case "look at the time" && day === 0) {
            console.log("it's only been a few hours, but time is still ticking");
            day++
        } else if (day > 0) {
            console.log("it's been " + day + "s! Will I make it out of here");
            day++
        }
        break;
    case "figure out where I am":
        console.log("Yeah, how did I end up here in the first place?");
        if (
        case "figure out where I am" && day === 0) {
            console.log("This is a good checkpoint");
            day++
        }
        break;
    case 'run':
        console.log("Dry your eyes, find a direction, and hope for the best");
        break;
    case 'give up':
        console.log('Thanks for trying, have fun, where ever you are...');
        break;
    default:
        console.log("you fall back unconscious, hoping to wake again");
        day++;
        if (
        default) {
            return user;
        }
        if (
        case 'run' ||
        case 'give up') {
            console.log("It would have ended up coming down to this option anyway");
        }
}

如果您进行更改以停止在 if 语句中使用单词 case，它将起作用，例如它应该看起来像这样与 user 进行比较来自 case 语句的变量：

if (user === "look at the time" && day === 0) {
    console.log("it's only been a few hours, but time is still ticking");
    day++
} else if (day > 0) {
    console.log("it's been " + day + "s! Will I make it out of here");
    day++
}

在这种情况下，比较 user === "look at the time" 是多余的，因为该逻辑已经在 switch 语句本身中进行了评估。我只是将它包括在内，以便您可以看到如何与 user 变量进行比较，但它可以完全排除在这种情况下并具有相同的效果。
