Hi Arthur,

You're doing great.

But the 3rd task says to alert() the third item. Right now, your code is trying to alert() the 5th item, which doesn't exist. Remember, arrays use zero indexing, so the 3rd item with be at index 2.

Keep it up! :) :dizzy:

Javascript array starts with 0 index.

For your array

var snacks = ["chips", "popcorn", "crackers"]
  • chips is at 0 index and is accessed by snacks[0]
  • popcorn is at 1 index and is accessed by snacks[1]
  • crackers is at 1 index and is accessed by snacks[2]

snacks[4] does not exist in your array

If you count the snack list starting at 0, the third snack would be 2

Oh! I'm stupid... Thanks guys!

Nah, never "stupid". And don't worry... we all have and still do make silly mistakes every now and again. It keeps us on our toes. :smile: :thumbsup: ?‍♂️
