A website needs a list where users can rank their favorite foods. Write the setup function, which should register click handlers on all Up! and Down! buttons. The Up! button should move the list item one place up in the list, while Down! button should move the list item one place down in the list.
For example, consider this code:
document.body.innerHTML = `<ol>
<li><button>Up!</button>Taco<button>Down!</button></li>
<li><button>Up!</button>Pizza<button>Down!</button></li>
<li><button>Up!</button>Eggs<button>Down!</button></li>
</ol>`;
setup();
If the button Up! button in Pizza list item is clicked, Pizza should be the first item in the list, while Taco should be the second item.
- Example case: Wrong answer
- Elements can move up: Wrong answer
- Elements can move down: 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?
