587d7b84367417b2b2512b35 捕获拼错的变量名和函数名 1 301186 catch-misspelled-variable-and-function-names

--description--

console.log()typeof方法是检查中间值和程序输出类型的两种主要方法。 现在是时候了解一下 bug 出现的常见的情形。一个语法级别的问题是打字太快带来的低级拼写错误。

变量或函数名的错写、漏写或大小写弄混都会让浏览器尝试查找并不存在的东西并报出“引用错误”。JavaScript 变量和函数名称区分大小写。

--instructions--

修复代码中的两个拼写错误,以便netWorkingCapital计算有效。

--hints--

检查计算 netWorkingCapital 值时使用的两个变量的拼写是否正确,控制台应该输出 "Net working capital is: 2"。

assert(netWorkingCapital === 2);

代码中不应存在拼写错误的变量。

assert(!code.match(/recievables/g));

应在代码中声明并正确使用receivables变量。

assert(code.match(/receivables/g).length == 2);

代码中不应存在拼写错误的变量。

assert(!code.match(/payable;/g));

应在代码中声明并正确使用payables变量。

assert(code.match(/payables/g).length == 2);

--seed--

--seed-contents--

let receivables = 10;
let payables = 8;
let netWorkingCapital = recievables - payable;
console.log(`Net working capital is: ${netWorkingCapital}`);

--solutions--

let receivables = 10;
let payables = 8;
let netWorkingCapital = receivables - payables;
console.log(`Net working capital is: ${netWorkingCapital}`);
