Welcome to the Treehouse Community
Looking to learn something new?
not quite sure if I typed this out correctly?
can I please get some help with this array question
var arrayOfInts = [1,2,3,4,5,6] arrayOfInts.append ("7") [1,2,3,4,5,6] +

In appending the array, the quotation marks around the "7" mean it is a String; arrays are 'homogenous' and can only accept one type of data like Ints, Strings, Doubles etc.
// arrayOfStrings would look like ["this", "is", "a", "string"] arrayOfInts[0,1,2,3,4,5,6,7] arrayOfInts.append(7)
The String concatenation you've done at the bottom passes the challenge too.
I hope this helps :)
