Chevrotain may rely on modern standard library APIs. Check the relevant `tsconfig*.json` files and package `engines` fields for exact runtime requirements. Legacy runtimes are not supported. If you need to support older browsers, transpilation and polyfills may be required. ## Contributions Contributions are **greatly** appreciated.
