The following XML represents a family tree:

<James>
    <Dave></Dave>
    <Mike></Mike>
    <Sarah></Sarah>
</James>

Implement the closestRelative function so that it returns the parent's closest relative whose name matches the relativeName and obeys the following rules:

  • The parent parameter is a jQuery selector of which the closest relative will be a descendant.
  • Each member of the family, including children, may also be a parent to one or more children.
  • Children are more closely related to the parent than grandchildren.
  • If several children in the same generation have the same name then the first child in the tree is considered the closer.
  • If no matching relative is found the function should return an empty jQuery object.

For example, closestRelative($('James'), 'Mike') should return the jQuery object wrapping <Mike></Mike>.

  •   Several generations: Wrong answer
  •   Children with the same name: Wrong answer

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...
