Parse Markdown Frontmatter with JavaScript

Frontmatter within a Markdown file is a way to add meta properties to a document. If you want to parse Frontmatter (for example with markdown-it), you can use a package called front-matter for that. There are also other packages, but this seems to be the best maintained and most used one.

• https://www.npmjs.com/package/front-matter

(Parsing Frontmatter yourself is possible, too. It has some gotchas, though.)
