Ruby

Hi

In irb i wrote 3.time(puts “dsds”) and it doesn’t work why?
Here i pasted log:

irb(main):027:0> 3.times(puts “Hello!”)
(irb):27: warning: parenthesize argument(s) for future version
Hello!
ArgumentError: wrong number of arguments (1 for 0)
from (irb):27:in `times’
from (irb):27

You don’t have a block:
3.times { puts “dsds” }

i find this alot better then blocking it

do … end is also a block. Just another way to write it.
