我是 javascript 的新手，我在下面编写了简单的函数。我想知道功能打击给了我未定义的东西。下面的函数有什么错误吗？

    return ["crown", "anchor", "heart", "spade", "club", "diamond"]
    [rand(0, 5)];
}

console.log(randFace())

尝试这个，

function randFace() {
    let faces = ["crown", "anchor", "heart", "spade", "club", "diamond"]
    return faces[Math.floor(Math.random() * faces.length)];
}

console.log(randFace())
