Note

As of 2024, this project has adopted Rust as its primary programming language, replacing JavaScript. See the issue for the details.

Contributing

I have limited availability to consistently maintain this project, as my time is primarily allocated to cutting new releases and implementing fixes on an ad hoc basis.
