Meriyah is a highly performant and stable JavaScript parser, currently at version 7.1.0, designed for 100% compliance with the ECMAScript® 2024 (ES-262 15th Edition) standard. It provides an ESTree-compatible Abstract Syntax Tree and operates without backtracking, contributing to its low memory footprint. While it actively supports Annex B (Web Browsers) features, JSX parsing, and select TC39 Stage 3 proposals like Decorators and JSON Modules via an opt-in `next` flag, it notably does *not* support TypeScript or Flow syntax. The project maintains a steady release cadence, frequently updating to reflect the latest ECMAScript specifications and address bug fixes, as evidenced by recent v6 and v7 patch and minor releases, ensuring it remains a cutting-edge tool for syntactic analysis.
