# Numeric separator support for Acorn

[![NPM version](https://img.shields.io/npm/v/acorn-numeric-separator.svg)](https://www.npmjs.org/package/acorn-numeric-separator)

This is a plugin for [Acorn](http://marijnhaverbeke.nl/acorn/) - a tiny, fast JavaScript parser, written completely in JavaScript.

It implements support for numeric separators as defined in the stage 3 proposal [Numeric Separators](https://github.com/tc39/proposal-numeric-separator).

## Usage

This module provides a plugin that can be used to extend the Acorn `Parser` class to parse numeric separators.
You can either choose to use it via CommonJS (for example in Node.js) like this

```javascript
const {Parser} = require('acorn');
const numericSeparator = require('acorn-numeric-separator');
Parser.extend(numericSeparator).parse('100_000');
```

or as an ECMAScript module like this:

```javascript
import {Parser} from 'acorn';
import numericSeparator from 'acorn-numeric-separator';
Parser.extend(numericSeparator).parse('100_000');
```
