JavaScript runtime with stackful coroutines. Pros: - Massive outburst of scripts running as coroutines - Simple API without using async/await yet running in parallel - Built for Linux (x86_64, arm6, arm7, arm8, arm64), Windows (x86, x86_64, arm64), MacOS(x86_64, arm64), iOS(arm64), Android (arm7, arm64, x86, x86_64) - Memory arenas per script/coroutine using single threaded non lockable memory - Polymorphic c/c++ allocators sharing same memory arena as script context - Similar to Flutter's Isolates for message passing between threads and scripts/coroutines - Caching the precompiled script modules for faster reuse - LRU cache for small script files and file handles - Thread pool dynamically grows and shrinks depending of workload - Using io_uring optimizations for Linux - asynchronous threads, processes and pipes (thank you boost::asio) - Predictive branching favoring desired outcomes (sounds smart, but it's a macro on every if statement) - There are no mutexes or any synchronization/ blocking calls - JavaScript library (quickjs) is using reference counting for it's garbage collections which makes c/c++ binding more deterministic and memory efficient - C/C++ metatemplates are used to "fuse" dynamic JavaScript objects with statically typed C++ counterparts Cons: - no debugger - no final release date - no stable API - no complete test coverage - plan to open-source it until spring of 2023
