Agile Web Development with Rails 7: Add details when they become relevant [solved]

Title: Name of book: description (5228 on Kindle, page 153 )

From
format.turbo_stream { @current_item = @line_item }

To
format.turbo_stream

The { @current_item = @line_item } become relevant a few pages later in page 155. For the new commercial (my case) it creates the impression that format.turbo_stream must have some parameters.

Good catch! Fixed.
