you can add values to an array by concatenating two arrays which basically means that you're adding one array to another. In this case I'm also using the addition assignment operator (+=) to add the second array to the existing arrayOfInts and assign it in one step.
Also note that you have to remove the let keyword in the last line of your code because you already created it as a variable and you want to change it.
Like so:
// Enter your code below
var arrayOfInts = [1, 2, 3, 4, 5, 6]
// Using the append method
arrayOfInts.append(7)
// Using concatenation
arrayOfInts += [8]
I hope that helps! :)
