## Description
|
|
<section id='description'>
|
|
The <code>console.log()</code> and <code>typeof</code> methods are the two primary ways to check intermediate values and types of program output. Now it's time to get into the common forms that bugs take. One syntax-level issue that fast typers can commiserate with is the humble spelling error.
|
|
Transposed, missing, or mis-capitalized characters in a variable or function name will have the browser looking for an object that doesn't exist - and complain in the form of a reference error. JavaScript variable and function names are case-sensitive.

|
## Instructions
|
|
<section id='instructions'>
|
|
Fix the two spelling errors in the code so the <code>netWorkingCapital</code> calculation works.

## Tests

<section id='tests'>
|
|
|
|
```yml
|
|
tests:
|
|
- text: 'Check the spelling of the two variables used in the netWorkingCapital calculation, the console output should show that "Net working capital is: 2".'
|
|
testString: 'assert(netWorkingCapital === 2);'
|
|
- text: There should be no instances of mis-spelled variables in the code.
|
|
testString: assert(!code.match(/recievables/g));
|
|
- text: The <code>receivables</code> variable should be declared and used properly in the code.
|
|
testString: assert(code.match(/receivables/g).length == 2);
|
|
- text: There should be no instances of mis-spelled variables in the code.
|
|
testString: assert(!code.match(/payable;/g));
|
|
- text: The <code>payables</code> variable should be declared and used properly in the code.
|
|
testString: assert(code.match(/payables/g).length == 2);
|
|
