# awesome syntax-tree [![awesome][awesome-badge]][self]



[](https://unifiedjs.com)



> A curated list of awesome syntax-tree, **[unist][]**, **[mdast][]**

> (markdown), **[hast][]** (HTML), **[xast][]** (XML), **[esast][]** (JS), and

> **[nlcst][]** (prose) resources.



**syntax-tree** is an organization housing **[unist][]** and its main

implementations **[mdast][]**, **[hast][]**, **[xast][]**, **[esast][]**, and

**[nlcst][]**.

**[unist][]** is a specification for syntax trees that comes with a big

ecosystem of utilities in JavaScript for working with those trees.

On top of **[unist][]** and its implementations sits the rest of

**[unified][]** that does all kinds of things to process content.
