 It was created as an experimental alternative, faster [React.js JSX](http://facebook.github.io/react/docs/jsx-in-depth.html) parser. Later, it replaced the [official parser](https://github.com/facebookarchive/esprima) and these days is used by many prominent development tools.

 ## Transpiler
 
 Please note that this tool only parses source code to JSX AST, which is useful for various language tools and services. If you want to transpile your code to regular ES5-compliant JavaScript with source map, check out [Babel](https://babeljs.io/) and [Buble](https://buble.surge.sh/) transpilers which use `acorn-jsx` under the hood.
