Subject: what's the difference between these two snippets of ruby?

Sorry I couldn't help the line wrapping. Thanks in advance.

parent_path =
File.expand_path(config['parent'],
File.dirname(yaml_path)).gsub('${project_dir}',
PROJECT_ROOT)


config['parent'].gsub!("${project_dir}", PROJECT_ROOT)
parent_path = File.expand_path(config['parent'],
File.dirname(yaml_path))
