How can I access keys from an array stored in a variable?

I am trying to access the name key of the variable drawnCard in this code and I cannot figure out why it does not work.

Would you mind checking out the end of my Javascript code ?

Please don't mind the highly probable beginner's coding...

Thanks!!

When splicing the one element out of your array, it is still returning it as an array.

Therefore to get the name you would need to use:

var drawnCard = deck.splice(randomCard, 1);
console.log(drawnCard[0].name) // note the index here

Or you could extract the first item from the splice when pulling it out like so:

var drawnCard = deck.splice(randomCard, 1)[0]; // and the first index here
console.log(drawnCard.name)

Do this to your Code

var randomCard = Math.floor(Math.random() * deck.length);
console.log(randomCard)
var drawnCard = deck.splice(randomCard, 1)[0];
console.log(drawnCard.name);
