🔍 Using dig to Safely Access Nested Arrays

Ruby’s dig method lets you fetch deeply nested elements without chaining [] calls or worrying about nil errors. This simplifies traversing multi-dimensional arrays or JSON-like structures.

nested = [[{id: 1}, {id: 2}], [{id: 3}]]
# Without dig:
val = nested[0] && nested[0][1] && nested[0][1][:id]
# With dig:
val = nested.dig(0, 1, :id)  # => 2
