Function appendChildren should add a new child div to each existing div. New divs should be decorated by calling decorateDiv.
For example, after appendChildren is executed, the following divs:
<div id="a">
<div id="b">
</div>
</div>
should take the following form (assuming decorateDiv does nothing):
<div id="a">
<div id="b">
<div></div>
</div>
<div></div>
</div>
The code below should do the job, but for some reason it goes into an infinite loop. Fix the bugs.
- Example case: Error
- Appending divs: Error

Screening Applicants: The Good, the Bad and the Ugly
Since we’re all biased and we use incorrect proxies, why not just outsource hiring to experts or recruitment agencies? After all, they’ve been screening people for many years, so they must know how to do it right?
Not really. I was surprised to discover that many experts disagree with each other. Everybody praises their pet method and criticizes the others. Many of these methods look legitimate, but are based on...
