How to pass multiple arguments into a Ruby method
ruby
Solution
It's the space before the parens. Remove it. Instead of treating `array_1` and `array_2` as args, it's treating it as a parenthesized expression (with the whole expression being one arg) and complaining about the comma. Your code should look like
parser(array_1, array_2)
Incidentally, Ruby 1.8.7 seems to simply emit a warning about this before behaving correctly.
Problem
Passing one argument at a time into the parser method works. More than one and it generates "syntax error, unexpected ',', expecting ')' (SyntaxError)" ``` $array = [] array_1 = %w(tuna salmon herring) array_2 = %w(crow owl eagle dove) def parser (*argument) argument.each do |item| $array << item end end parser (array_1, array_2) # taking multiple arguments generates error $array.flatten! puts $array ```
