Ruby: Calling variable from array?

Question

How do I call a variable from an array? Trying to make this:

hello_world = "Hey" array = [ '#{hello_world} ho' ] array.each do |a| puts a end

say ["Hey ho"] instead of ["\#{hello_world} ho"].

Do as below -

hello_world = "Hey" array = [ "#{hello_world} ho" ] array # => ["Hey ho"] array.each do |a| p a end # >> "Hey ho"

Single-quoted strings disabling interpolation, but double-quote strings allow interpolation.

Remember - Interpolation may be disabled by escaping the “#” character or using single-quote strings:

'#{1 + 1}' #=> "\#{1 + 1}"
