Ruby %w empty value -
how add empty string select option %w(mr ms mrs miss)?
i can ['', 'mr', 'ms', 'mrs', 'miss'] use %w. thx!
use unshift prepended object front:
=> %w(mr ms mrs miss).unshift "" #> ["", "mr", "ms", "mrs", "miss"] pretty version without brackets.
ok update:
=> %w(#{} mr ms mrs miss) #> ["", "mr", "ms", "mrs", "miss"] explain:
%w- allow interpolation%w- not allow interpolation#{}- empty string
