I have code:
arr.to_h { |id| [id, 0] }Then I run rubocop with autocorrect and get:
arr.index_with { |_id| 0 }However:
arr = [1, 2, 3]
arr.to_h { |id| [id, 0] } # => {1=>0, 2=>0, 3=>0}
arr.index_with { |_id| 0 } # => {1=>0, 2=>0, 3=>0}
arr = nil
arr.to_h { |id| [id, 0] } # => {}
arr.index_with { |_id| 0 } # NoMethodError: undefined method `index_with' for nil:NilClassRuboCop
