非法返回语句错误

Question

我的退货声明有什么问题？

var creditCheck = function (income) {
    var val = income;
    return val;
};
if (creditCheck > 100) {
    return "You earn a lot of money! You qualify for a credit card.";
} else {
    return "Alas, you do not qualify for a credit card. Capitalism is cruel like that.";
}
console.log(creditCheck(75));

Answer 1

您的return陈述不属于任何功能.您只能return在一个函数中使用.

(你也在比较一个函数和一个整数,在if (creditCheck > 100)- 你的意思是在那里调用函数吗？)
