Thank you for your response.
first think of ‘n’ as 5. Ok, I understand this
if n is less than 1 then return an array, yes I understand this
else (if the n is greater or equal 1) get the return value of countup(5-1) and push to that value n (which is 5). what is the return value of ‘countup(5-1)’?
what is the value of countup(5-1) in other words countup(4) ?
‘n’ in this context is 4. how does n become 4? n-1 is 4, but how does n become 4? How can n be the same as n-1?
if n is less than 1 it return an array,
else (if the n is greater or equal to 1) get the value of countup(4-1) and push to that value ‘n’ ( which is 4). Again, I don’t understand how the value of n has changed. we called the function with ‘5’ so how can it now be 4? n-1 is 4, but ‘n’ itself is still 5, right?
a question for you.
what is the value of countup(4-1) ? this would be countup(3)
Also - I think .push is used to add to the end of an array, but where are we actually creating the array to add to?
