Basic question. Instead of adding ‘\n’ between the elements: >> puts #{[1, 2, 3].join(‘\n’)}

Basic question.

Instead of adding ‘\n’ between the elements:

>> puts "#{[1, 2, 3].join('\n')}"
1\n2\n3

I need to actually add the line feed character, so the output I expect when printing it would be:

1

2

3

What’s the best way to do that in Ruby?

    You need to use double quotes.

    puts "#{[1, 2, 3].join("\n")}"

    Note that you don’t have to escape the double quotes because they’re within the {} of a substitution, and thus will not be treated as delimiters for the outer string.

    However, you also don’t even need the #{} wrapper if that’s all your doing – the following will work fine:

    puts [1,2,3].join("\n")
