+> [!NOTE]
+> Brace expansion (e.g., `{a,b}`) is a feature of your shell (like bash or zsh). The shell expands these patterns into multiple arguments before passing them to TSSLint. For glob patterns (e.g., `*`), TSSLint uses the `glob` library to resolve them internally.

 > [!TIP]
 > TSSLint focuses on diagnostic fixes and does not include a built-in formatter. It is recommended to run a dedicated formatter like **Prettier**, **dprint**, or **oxfmt** after running TSSLint with `--fix`.
