Ruby: Calling variable from array? -

-

how call variable array? trying make this:

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

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

do below -

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

single-quoted strings disabling interpolation, double-quote strings allow interpolation.

remember - interpolation may disabled escaping “#” character or using single-quote strings:

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