Question

我正在为一所学校的项目工作，我正在寻找为什么我的代码无法运行的原因。我确信这是一件我看不到的简单事。任何帮助都会很棒。

   const THIRTYFIVE = 0.35;
   const THREENINETYSIX = 0.396;


   function calculateTaxes(inTaxableIncome, inTaxRate)
   {
       var income = parseInt(inTaxableIncome);
       var rate = parseFloat(inTaxRate);
       var taxesOwed = income * rate;
       return taxesOwed;
   }

   function refundOrPay(inTaxesOwed, inTaxesPaid)
   {
       var taxesOwed = parseInt(inTaxesOwed);
       var taxesPaid = parseInt(inTaxesPaid);
       var taxDifference = taxesOwed - taxesPaid;

        }

        document.writeln("Thank you for using COP 2500 Tax Service!");

Answer 1

有一些拼写错误（函数名称中的空格，变量的错误大小写）和缺少函数getTaxRate()

在此处检查版本1和2之间的变形：http://plnkr.co/edit/0sLVnlTBwcHeYYOBvycO
