Garbage collection and closures
Me, Surma, and Jason were hacking on a thing, and discovered that garbage collection within a function doesn't quite work how we expected. function demo() { const bigArrayBuffer = new ArrayBuffer(100_000_000); const id = setTimeout(() => { console.log(bigArrayBuffer.byteLength); }, 1000); return () => clearTimeout(id); } globalThis.cancelDemo = demo(); With the above, bigArrayBuffer is leaked fore
Porffor
A from-scratch experimental ahead-of-time JS engine Porffor is a unique JS engine/compiler/runtime, compiling JS code to WebAssembly or native ahead-of-time. It is limited for now; intended for research, not serious use! Wasm compilation Porffor's WebAssembly output is much faster and smaller compared to existing JS -> Wasm projects. This is because Porffor compiles JS AOT instead of bundling an i
Gleam
Gleam is a friendly language for building type-safe systems that scale! The power of a type system, the expressiveness of functional programming, and the reliability of the highly concurrent, fault tolerant Erlang runtime, with a familiar and modern syntax. Reliable and scalable Running on the battle-tested Erlang virtual machine that powers planet-scale systems such as WhatsApp and Ericsson, Glea
GitHub - ohmjs/ohm: A library and language for building parsers, interpreters, compilers, etc.
Ohm is a parsing toolkit consisting of a library and a domain-specific language. You can use it to parse custom file formats or quickly build parsers, interpreters, and compilers for programming languages. The Ohm language is based on parsing expression grammars (PEGs), which are a formal way of describing syntax, similar to regular expressions and context-free grammars. The Ohm library provides a
