LibJS test262 results
Introduction
These are the results of the SerenityOS JavaScript engine, LibJS, running the official ECMAScript conformance test suite test262 as well as the test262 parser tests. All tests are re-run and the results updated automatically for every push to the master branch of the repository on GitHub. Dates and times are shown in your browser's timezone.
Some milestones:
- Development of the engine started in March 2020 (see this YouTube video)
- Continuous running of test262 started in June 2021 (see this PR on GitHub) — results before that time are not available
- In October 2021 David reimplemented the test runner to use a streaming architecture (see this PR on GitHub), resulting in a large performance improvement (the part that looks like a cliff).
If you have any questions or want to help out with improving these
test scores, feel free to get in touch on the
