## Description
|
||
<section id="description"> <code>console.log()</code>和<code>typeof</code>方法是检查中间值和程序输出类型的两种主要方法。现在是时候进入错误所采用的常见形式了。快速打字机可以同意的一个语法级问题是简单的拼写错误。变量或函数名称中的转置，丢失或错误大写字符将使浏览器查找不存在的对象 - 并以引用错误的形式进行抱怨。 JavaScript变量和函数名称区分大小写。 </section>

||

|
||
<section id="instructions">修复代码中的两个拼写错误，以便<code>netWorkingCapital</code>计算有效。 </section>

- text: 代码中不应存在拼写错误的变量。
|

testString: 'assert(!code.match(/recievables/g), "There should be no instances of mis-spelled variables in the code.");'
|
||
- text: <code>receivables</code>在代码中声明并正确使用应<code>receivables</code>变量。
