So first, on line 4, I was actually testing another solution which involves that select-until-plugin, but was not used in the final solution, so don't mind that 😅. You can also delete the console.log(cards.size) since that was only used for debugging.

Here are some explanations to the code: On line 9-10:

• we create a new list named getCards.
• Upon calling that list inside a square bracket e.g. [getCards], it would create a new JavaScript Set (which is an object that allows you to store unique items), then set is then referenced with the variable cards.
• After creating the Set, we then call the selectCards list.

On 14-15:

• We create a new list called selectCards.
• Upon calling that, it would first check if the cards.size (or number of items in the cards Set).
• If the number is less than the specified num then it would 'add' an output on the Set with cards.add(output.evaluateItem).
• The output is where you get the randomized cards that you have set up. We use .evaluateItem to it so it would only be a 'text' i.e. something like You have a 7 of spades from a Gammorah deck. and not You have [jokerornonjoker] from {a} [establishment] deck.
• After adding to the Set, we then call again the selectCards, this will go through again the check, and if not, it would add again to the Set and go into a loop until the check for the size of the Set and the specified number has been met.
• If the number is now greater than the specified num, it would then stop from the Loop and output the contents of the Set.
• The Set is transformed into an Array with Array.from(cards) and using .selectAll and .joinItems('<br>') will neatly format them.
