I was always under assumption that the block accepts the return value
of the iterator as the argument to the block, but look at this:
Array.new(500) do | i |
puts i
end
I expect i to be an array instance with 500 indexes all will nil
values. However, what it returns is indeed an array with 500 indexes
all with nil values BUT before it returns that array instance, the
block appears to execute 500 times passing an actual integer value
into the block incrementing by 1 each time. I dont understand why this
is happening.
thanks for response
