How do I loop through elements of a bash array variable passed to a Ruby script via terminal?

Question

I have a Bash file called test.sh:

#!/bin/bash
arr=([email protected] [email protected])
ruby testScript.rb $arr

And here's testScript.rb:

ARGV.each{|a| p a}

When I run ./test.sh in the terminal, I get this output:

"[email protected]"

I want my Ruby script to loop through all elements in the Bash array variable $arr. How do I fix my code to do this?

In the bash script, pass the array like this:

ruby testScript.rb "${arr[@]}"
