stage 3 proposal support for Acorn

This is a plugin for Acorn - a tiny, fast JavaScript parser, written completely in JavaScript.

It implements support for all missing ECMAScript stage 3 proposals. Neither loose mode nor walk are currently supported.

• Numeric Separators via acorn-numeric-separator
• Class field declarations via acorn-class-fields
• Private methods and getter/setters for JavaScript classes via acorn-private-methods
• Static class features via acorn-static-class-features
• Logical assignments via acorn-logical-assignment

Usage

This module provides a plugin that can be used to extend the Acorn Parser class:

const {Parser} = require('acorn');
const stage3 = require('acorn-stage3');
Parser.extend(stage3).parse('100_000n');
