Ruby basics - Method Arguments
I am using the exact same code as Jason:
def add(a) puts a + 2 end add(2)
But its outputing the error code he showed.
irb(main):006:0> ruby methods.rb NoMethodError: undefined method `rb' for #<Array:0x007f7994a30650> from (irb):6 from /usr/local/bin/irb:11:in `<main>'
I am confused.
You're running the script from within irb. You just need to run
ruby methods.rb from the command line instead.
