Hi guys !
Is there a method like this :
Array.new(n) { |i| …}
but that works with an existing array ? Like that :
array.append(5) { |i| … }
?
Thank U !
Sébastien

Dear Sbastien,
You can Array#fill at the end
ary.fill(5…9) { |i| i*10 }
=> [0, 1, 2, 3, 4, 50, 60, 70, 80, 90]
You can overwrite previous values
ary.fill(0…4) { |i| i*2 }
=> [0, 2, 4, 6, 8, 50, 60, 70, 80, 90]
This is cool, any where inside the array, you can play… Nice +1.
Dear Sbastien,
Try the 2 options bellow and see if any fits what you need.
ary = Array.new (5) { |i| i }
=> [0, 1, 2, 3, 4]
ary.fill(5…9) { |i| i*10 }
=> [0, 1, 2, 3, 4, 50, 60, 70, 80, 90]
ary.fill(0…4) { |i| i*2 }
=> [0, 2, 4, 6, 8, 50, 60, 70, 80, 90]
ary.concat Array.new (5) { |i| i*100 }
=> [0, 2, 4, 6, 8, 50, 60, 70, 80, 90, 0, 100, 200, 300, 400]
Hope it helps you,
