At the same time, it consumes all the ES6+JSX syntax that can be consumed by Esprima-FB (this is proved by [official tests](https://github.com/RReverser/acorn-jsx/blob/master/test/tests-jsx.js)). - -**UPDATE [14-Apr-2015]**: Facebook implementation started [deprecation process](https://github.com/facebook/esprima/issues/111) in favor of Acorn + Acorn-JSX + Babel for parsing and transpiling JSX syntax. +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 the [babel transpiler](https://babeljs.io/) which uses `acorn-jsx` under the hood. +Please note that this tool only parses source code to JSX AST, which is useful for various language tools and services.
