Thanks for sharing this comprehensive list of Yarn commands! It's a handy reference for anyone working with Yarn for JavaScript package management. These commands cover everything from basic package installation and management to more advanced tasks like setting defaults, managing global packages, and checking for outdated dependencies.

One additional tip I'd like to share is to consider using Yarn workspaces when working on projects with multiple packages/modules. Yarn workspaces can simplify package management for monorepos by allowing you to manage dependencies and scripts across multiple packages in a single repository.

Overall, this gist is a valuable resource for both beginners and experienced developers using Yarn. Great job putting it together!
