standard-markdown

Test your Markdown files for Standard JavaScript Style™. Current stable version is 7.1.0 (requires Node >=11). Release cadence is sporadic, with major versions bumping the underlying `standard` dependency. Key differentiators: it lints JavaScript code blocks inside Markdown files (GitHub-Flavored `js`/`javascript` blocks), disables certain rules inappropriate for inline code (e.g., no-undef, no-unused-vars), and supports auto-fixing via `standard`. Alternatives include `remark-lint` for general Markdown linting or manual extraction of code blocks.
