Check If String Has JSON Inside

        Two very simple methods of checking whether string has JSON inside ...

More accurate one:

module JSON
  def is_json?(string)
    begin
      parse(string).all?
    rescue ParserError
      false
    end
  end
end

Less accurate one (but quicker):

class String
  def is_json?
    self[0..0] == '{'
  end
end
