# --description--
|
|
|
|
The `console.log()` and `typeof` 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--
|
|
|
|
Fix the two spelling errors in the code so the `netWorkingCapital` calculation works.
|
|
|
|
# --hints--
|
|
|
|
Check the spelling of the two variables used in the netWorkingCapital calculation, the console output should show that "Net working capital is: 2".
|
|
|
|
```js
|
|
assert(netWorkingCapital === 2);
|
|
```
|
|
|
|
There should be no instances of mis-spelled variables in the code.
|
|
|
|
```js
|
|
assert(!code.match(/recievables/g));
|
|
```
|
|
|
|
The `receivables` variable should be declared and used properly in the code.
|
|
|
|
```js
|
|
assert(code.match(/receivables/g).length == 2);
|
|
```
|
|
|
|
There should be no instances of mis-spelled variables in the code.
|
|
|
|
```js
|
|
assert(!code.match(/payable;/g));
|
|
```
|
|
|
|
The `payables` variable should be declared and used properly in the code.
|
|
|
|
```js
|
|
assert(code.match(/payables/g).length == 2);
|
|
```
