Cannot append to an array."It looks like task 1 is no longer passing"

var arrayOfInts = [1,2,3,4,5,6] arrayOfInts.append(7) arrayOfInts = arrayOfInts + [8,9]

// Enter your code below
var arrayOfInts = [1,2,3,4,5,6]
arrayOfInts = arrayOfInts + [8,9]

Hi there! You're doing fine, but there's just a misunderstanding in the second part of Step 2. It asks you to add one new element using append, and another new element using concatenation. However, you are using concatenation to add two new elements, so the array doesn't look like the challenge is expecting. If I simply erase the ,9 from the [8, 9], your code passes step 2.

Hope this helps! :sparkles:
