Analyn,

question 2. Leave the data array in place. Add another line of code that creates a second array named assorted. Assign one string value, a number and a Boolean value (like true or false) to the array. The complete assorted array should have 3 values total.

are you still having problems with this question?

To create a new array called "shoppingList" that has the items "carrots" "milk" and "eggs" in it, you would use this code:

var shoppingList = ["carrots", "milk", "eggs"];

The var keyword is used because you are creating a new variable. An array is just a more complicated variable that what you are used to. You only use the var keyword when you are creating the array. Once you have created the shoppingList array you will not need to put the var keyword in front of it again.

Analyn- I am still learning Javascript but this is a quote from one of my coding textbooks: "An array is a variable containing multiple values. Any variable may be used as an array." So if an array is a variable then it would need to be identified as var.

Hi Analyn, you should use always use the var keyword when creating a new array. It looks like this:

var fruits = [apple, banana, pear, strawberry];

For that lesson, I was able to complete the exercise with this answer: var data = [1, 2, 3];

I watched the video and was also having trouble with that one. Once I reviewed the video the answer came to me. If you do the following, you should pass the 2nd part of the challenge without a problem:

var assorted = ['apples', 99, true];

You can assign different values than what I have and it should work. Hopefully, this helps.
