Question

我一直收到这个错误： - 看起来你的功能没有返回'唉你没资格获得信用卡。资本主义是残酷的。“当收入参数为75时。

有人可以告诉我我做错了什么吗？干杯：）

var creditCheck = function(income)
if(income >= 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.";
}


creditCheck(75);
creditCheck(125);
creditCheck(100);

Answer 1

var creditCheck = function(income) {
    if(income >= 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.";
    }
};

此外，您正在返回一个字符串，您还没有将它打印到屏幕或控制台，或者您什么也看不见。

Answer 2

如何打开和关闭该功能：

var creditCheck = function (income) {
    if (income >= 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.";
    }
}
