Project built during Jonas Schmedtmann's courses on UDEMY. THE WEBSITE
- Systematically store my access to the DOM in variable to make their utilization easier
- Use the classList methode to manipulate class in HTML attributes
- An addEventListener create an object of what he listen, and we can manipulate this object to listen a specific key of the keyboard for example
- The querySelector select only the first element that he meet. To select all the selector of a specific class, we use querySelectorAll. QuerySelectorAll gives us a objet that looks like an array, and we can itearte in this array using a classical for loop (that way we talk the same way to all the element returned by the querySelectorAll).
