Hey there johannestoikka,

It looks like this challenge is asking for a few parts:

  1. to append a value to the current array - this is what you have currently. Nice work.

2.a to also utilize concatenation (as opposed to the append method).

2.b to assign the results of the expression back to the arrayOfInts array

to use concatenation you can do so like this:

var sum = arrayOfInts + [7]

additionally to assign this new variable "sum" back to the original array you do so with the assignment operator like this:

sum = arrayOfInts

Hope this helps!


im good thx
