Chevrotain

TLDR

Introduction

Chevrotain is a blazing fast and feature rich Parser Building Toolkit for JavaScript with built-in support for LL(K). Grammars and 3rd party plugin for LL(*) grammars. It can be used to build parsers/compilers/interpreters for various use cases ranging from simple configuration files, to full-fledged programing languages.

Grammars are written as pure JavaScript sources without a code generation phase,
