quickjs

QuickJS is a small and embeddable JavaScript engine. It supports the ES2023 specification including modules, asynchronous generators, proxies and BigInt. Main Features: - Small and easily embeddable: just a few C files, no external dependency, 210 KiB of x86 code for a simple hello world program. - Fast interpreter with very low startup time: runs the 76000 tests of the ECMAScript Test Suite in less than 2 minutes on a single core of a desktop PC. The complete life cycle of a runtime instance completes in less than 300 microseconds. - Almost complete ES2023 support including modules, asynchronous generators and full Annex B support (legacy web compatibility). - Passes nearly 100% of the ECMAScript Test Suite tests when selecting the ES2023 features. A summary is available at Test262 Report. - Can compile JavaScript sources to executables with no external dependency. - Garbage collection using reference counting (to reduce memory usage and have deterministic behavior) with cycle removal. - Command line interpreter with contextual colorization implemented in JavaScript. - Small built-in standard library with C library wrappers.
