Question

Let’s say I have this array:

a = [0,1,2,3,4,5]

How would I get entries 2 and 4 (say) from the array? I’d love something like

x, y = a.entries_at(2, 4)

but I want something built-in. Is there anything in the Ruby stdlib that does this? It’s hard to google for.

Answer 1

You’re spot on with your guess. It’s called values_at:

irb(main):001:0> [0,1,2,3,4,5].values_at(2, 4)
=> [2, 4]
