[quote=引用 12 楼 ftiger 的回复:] 我的代码通过了，要返回值，而不是打印到控制台 

var getReview = function (movie) {
     
    switch(movie){
        case "Matrix":　//case语法错误　而且字符串要用引号括起来。
            return"good trip out";
         
        case "Princess Bride":
            return"awesome date night movie";
         
        case "Welcome to America":
            return"Amjad's favorite";
         
        case "Remember the Titans":
            return"love the sports";
         
        case "Why do I look like I'm 12?":
           return"The Ryan and Zach story";
         
         
        case "Fighting Kangaroos in the wild":
            return "Token Australian movie for Leng";
             
        //fault //这里是不是拼写错误？
        default :
        return"I don't know!";    
    }
 };
    getReview("Matrix");
Way to go! 通过了，谢谢你哈

if(movie in movies){ return movies[movie]; } return "I don't know!" －－－－－》 return movies[movie] || "I don't know!"; 另一个方法更简洁的原因 是 switch 可以抽象成一个map映射（配置重构）

Way to go! 另，另一个方法没通过，但这代码明显更精减。 

var getReview = function (movie) {
    var movies= {
        "Matrix":"good trip out",
        "Princess Bride" : "awesome date night movie",
        "Welcome to America" : "Amjad's favorite",
        "Remember the Titans" : "love the sports",
        "Why do I look like I'm 12?" : "The Ryan and Zach story",
        "Fighting Kangaroos in the wild" : "Token Australian movie for Leng"
    }
    
    if(movie in movies){
        return movies[movie];
    }
    return "I don't know!"
};
    getReview("Matrix");
Oops, try again! Better use a switch statement

这是改过之后的，但还是有错 var getReview = function (movie) { switch(movie){ case'Matrix': console.log("good trip out"); break; case'Princess Bride': console.log("awesome date night movie"); break; case'Welcome to America': console.log("Amjad's favorite"); break; case'Remember the Titans': console.log("love the sports"); break; case'Why do I look like I'm 12?': console.log("The Ryan and Zach story"); break; case'Fighting Kangaroos in the wild': console.log("Token Australian movie for Leng"); break; default: console.log("I don't know!"); } }; .getReview("Fighting Kangaroos in the wild");
