Numeric separator support for Acorn

This is a plugin for 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.

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

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

or as an ECMAScript module like this:

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