How to get a newline for ruby string in the array

Question

I am trying to output two values in an array with new line.

list = []
list << "hello"
list << "\n";
list << "testing"
puts "#{list}"

This will give hello, \n, testing instead of the following output:

hello
testing

How can I output this array with a newline?

You want to output a single string combining the array elements? `puts list.join` http://ruby-doc.org/core-2.5.0/Array.html#method-i-join — Michael Berkowski, Jan 03 '18 at 01:41
Or if you just had `list =["hello", "testing"]` you could join with the newline `puts list.join("\n")` — Michael Berkowski, Jan 03 '18 at 01:44

If you don't insert new-line-strings then `puts ['hello','testing']` will give you the output you desire. — Sagar Pandya, Jan 03 '18 at 03:58
just `puts list` gives what you want. don't use interpolation in this case — user3309314, Jan 03 '18 at 04:09

puts "#{list}"

This will print the array as it is, as a string.

puts list

This will print each element of the array in new line. This might be what you are looking for.
