## What it is
Emmet is a core library for parsing and expanding CSS-like abbreviations into HTML, CSS, and other markup/stylesheet code fragments. It powers editor plugins that dramatically speed up HTML and CSS authoring for web developers.

## Use cases
- expand css-like abbreviations into html markup
- generate nested html elements quickly while typing
- expand css property shortcuts like p10 into padding declarations
- parse emmet abbreviations into an ast for syntax highlighting
- produce code for haml, pug, jsx, scss and other syntaxes
- build custom editor plugins for html/css code generation

## When to avoid
- you just want emmet in your editor - install an editor plugin instead of this core module
- you need a general-purpose templating engine rather than abbreviation expansion
