Create array with empty string using %w[]

Question

To create an array with empty strings ['a', '', 'b', '', 'c'] (not one space strings ' '), using %W I can use %W[a #{} b #{} c], also I can concatenate arrays, but is it possible to create array with empty strings using just %w[]?

Answer 1

A couple of options

%W[a b c #{''} z]

%W[a b c] << " "

(I know this isn't using the %w{} syntax, but for good measure:

'a,b,c,,z'.split(',')
