Array question

ruby-talk
1

Hello,

I have a function like this:

def f(*args)
  #do something
end

and I have an array, say

a = [1,2,3]

Now I would like to call f() with the contents of the array i.e.

f(1,2,3) in this case (i.e. not f([1,2,3]) )

What is the most Rubyish way to accomplish this?

TIA,
Peter

Splat the array first with the * (splat) operator.
f(*a)
