This adds bigint, class-fields, numeric-separators, static-class features, private class methods and fields as dependency. That way it's possible to use these in combination with acorn to parse these language features. This also removes a couple of files that were not necessary for Node.js to reduce the code base.

# BigInt support for Acorn | ||
|
||
[![NPM version](https://img.shields.io/npm/v/acorn-bigint.svg)](https://www.npmjs.org/package/acorn-bigint) | ||
|
||
This is a plugin for [Acorn](http://marijnhaverbeke.nl/acorn/) - a tiny, fast JavaScript parser, written completely in JavaScript. | ||
|
||
It implements support for arbitrary precision integers as defined in the stage 3 proposal [BigInt: Arbitrary precision integers in JavaScript](https://github.com/tc39/proposal-bigint). The emitted AST follows [an ESTree proposal](https://github.com/estree/estree/blob/132be9b9ec376adbc082dd5f6ba78aefd7a1a864/experimental/bigint.md). | ||
|
||
## Usage | ||
|
||
This module provides a plugin that can be used to extend the Acorn `Parser` class: | ||
|
||
```javascript | ||
const {Parser} = require('acorn'); | ||
const bigInt = require('acorn-bigint'); | ||
Parser.extend(bigInt).parse('100n'); | ||
``` | ||
|
||
## License | ||
|
||
This plugin is released under an [MIT License](./LICENSE). |
