Question

How can I make the code below work, so that both puts display 1?

video = []
name = "video"

name[0] = 1

puts name[0] #gives me 1
puts video[0] #gives me nil

Answer 1

You can make it work using eval:

eval "#{name}[0] = 1"

I strongly advise against that though. In most situations where you think you need to do something like that, you should probaby use a hashmap. Like:

context = { "video" => [] }
name = "video"
context[name][0] = 1
