Questions & Answers

Q: What are the key methods needed to build a card matching game in JavaScript?

The key methods needed are flip (to flip a card), success (to handle a successful match), fail (to handle an unsuccessful match), reset (to reset the game), and shuffle (to shuffle the cards).

Q: How can you select all the cards for the game?

You can use the querySelectorAll method with the class name of the cards to select all the cards and store them in a node list. This node list can be looped through to perform operations on each card.

Q: How can you determine the selected card when a flip event occurs?

By using the keyword "this" inside the flip method, you can reference the card that was clicked and perform operations on it. By manipulating its class list, you can add the "flip" class to flip the card.

Q: How can you check if two flipped cards match?

You can compare the "data-image" attribute of the first card with that of the second card to check for a match. If they match, the success method is called. Otherwise, the fail method is called.
