Challenge from Brad Traversy & Florin Pop on Udemy '50 Projects in 50 Days'

3. JavaScript

• used window as target for eventlistener.. body worked as well, but window seems official(?)
• .key for space is blank, add 'space' manually: ${e.key === ' ' ? 'space' : e.key} <- here ? means then, : means else
• .keyCode is deprecated.
