dig 

        # Array.dig

(from ruby core)
---
    array.dig(index, *identifiers) -> object

---

Finds and returns the object in nested objects that is specified by
`index` and `identifiers`. The nested objects may be instances of
various classes. See [Dig Methods](rdoc-ref:dig_methods.rdoc).

Examples:
    a = [:foo, [:bar, :baz, [:bat, :bam]]]
    a.dig(1) # => [:bar, :baz, [:bat, :bam]]
    a.dig(1, 2) # => [:bat, :bam]
    a.dig(1, 2, 0) # => :bat
    a.dig(1, 2, 3) # => nil
