Ruby single and double quotes

Question

I\'ve recently been coding in Ruby and have come from Python, where single and double quotes made no difference to how the code worked as far as I know.

I moved to R

Answer 1

Single-quoted strings don't process escape sequence \ and they don't do string interpolation. For a better understanding, take a look at String concatenation vs. interpolation

To answer your question, you have to use "" when you want to do string interpolation:

name = 'world'
puts "Hello #{name}" # => "Hello world"

Using escape sequence:

puts 'Hello\nworld'       # => "Hello\nworld"
puts "Hello\nworld"       # => "Hello
                                world"
