Nil is always blank

nil.blank?        #=>  true

@return [TrueClass]

# File lib/gorillib/object/blank.rb, line 52
def blank?
  true

Calling try on nil always returns nil. It becomes specially helpful when navigating through associations that may return nil.

Examples

nil.try(:name) # => nil

Without try

@person && !@person.children.blank? && @person.children.first.name

With try

@person.try(:children).try(:first).try(:name)
# File lib/gorillib/object/try.rb, line 53
def try(*args)
  nil
