|
|
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.
