try(method_name = nil, *args)

Calling try on nil always returns nil. It becomes especially helpful when navigating through associations that may return nil.

nil.try(:name) # => nil

Without try

@person && @person.children.any? && @person.children.first.name

With try

@person.try(:children).try(:first).try(:name)
