map for a single value

Question

Hi,

There are a string and a proc object. The proc object is used to manipulate the string.

s = "10"

p = Proc.new { |i| i.to_i }

[s].map(&p).first #=> 10

This works. But is there a better way to do that when s and p are given?

Thanks.

Sam

Answer 1

>> p.call(s)
p.call(s)
=> 10

If I understand your question correctly, you just want the proc to manipulate the string?

Answer 2

in 1.9 you can do p.(s)
