You have a GroceryApp component, which receives a list of products, each one with name and votes. The app should render an unordered list, with a list item for each product. Products can be upvoted or downvoted.

By appropriately using React state and props, implement the upvote/downvote logic. Keep the state in the topmost component, while the Product component should accept props.

For example, passing the following array as products prop to GroceryApp [{ name: "Oranges", votes: 0 }, { name: "Bananas", votes: 0 }] and clicking the '+' button next to the Oranges should result in HTML like:

<div id="root">
      <span>Oranges</span> - <span>votes: 1</span><button>+</button> <button>-</button>
      <span>Bananas</span> - <span>votes: 0</span><button>+</button> <button>-</button>
HTML5, CSS3, React v16 (available as React and ReactDOM)

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...
