🔒 Safe Navigation Operator

The safe navigation operator (&.) helps avoid NoMethodError when calling methods on nil. It returns nil instead of raising an exception, making your code more concise and nil-safe.

user = nil
# Without safe navigation
# user.profile.name # => NoMethodError: undefined method `profile' for nil:NilClass

# With safe navigation
user&.profile&.name # => nil
