Implement the showCustomers function so that it renders customers as list items. The first argument to the function, customers, is an array of objects with the name and email properties. The second argument to the function, targetList, is an unordered HTML list to which each customer should be added as a separate list item.

The name and email properties should be added as two paragraphs inside the list item. The email HTML element should not be present at first, and its HTML element should be added / removed when the name is clicked.

For example, the following code:

document.body.innerHTML = `
<div>
  <ul id="customers">
  </ul>
</div>
`;
let customers = [{name: "John", email: "john@example.com"},
                 {name: "Mary", email: "mary@example.com"}];
showCustomers(customers, document.getElementById("customers"));

let customerParagraph = document.querySelectorAll("li > p")[0];
if(customerParagraph) {
  customerParagraph.click();
}
console.log(document.body.innerHTML);

Should render:

<div>
  <ul id="customers">
    <li>
      <p>John</p>
      <p>john@example.com</p>
    </li>
    <li>
      <p>Mary</p>
    </li>
  </ul>
</div>

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...
