Tell us what’s happening:
My code below works for the different edge cases provided. Was wondering if there is an exact syntax that FCC wants to pass this lesson.
this one prints [ 'head', 'shoulders', [ 'claw', 'tentacle' ], 'knees', 'toes' ]
it is failint two things: you have changed arr2, when instead it should stay invaried, and you have added the whole array insead of the elements of the array
Not sure as to why I sliced the first array. Can’t recall my thought pattern. Nevertheless, I did let copy = arr2.slice() and removed let firstArr = arr1.slice().
