Rails - Using %W

Question

I have the following which works well:

def steps
    %w[hello billing confirmation]
end

steps.first

But I want to do this:

  d         


        

Answer 1

%w() is a "word array" - the elements are delimited by spaces.

There are other % things:

%r() is another way to write a regular expression.

%q() is another way to write a single-quoted string (and can be multi-line, which is useful)

%Q() gives a double-quoted string

%x() is a shell command.
