# acorn-node

[Acorn](https://github.com/acornjs/acorn) preloaded with plugins for syntax parity with recent Node versions.

It also includes versions of the plugins compiled with [Bublé](https://github.com/rich-harris/buble), so they can be run on old Node versions (0.6 and up).

 - `allowHashBang: true`
 - `allowReturnOutsideFunction: true`

```js
var walk = require('acorn-node/walk')
```

The Acorn syntax tree walker. Comes preconfigured for the syntax plugins if necessary.
See the [acorn documentation](https://github.com/acornjs/acorn#distwalkjs) for details.
