An independent Rust rewrite of QuickJS, targeting semantic feature parity with the official QuickJS 2026-06-04 release and its ES2025 behavior.
The unsafe-free engine is runnable but incomplete. The current TypedArray
stack includes the shared 12-class kernel, in-place mutation, indexed search,
QuickJS-shaped find/findIndex/findLast/findLastIndex,
every/some, forEach, reduce/reduceRight, species-aware
map/filter and slice/subarray, plus non-species with and
toReversed, dedicated join/toLocaleString, inherited toString, and
QuickJS-shaped sort/toSorted, certified entries/keys iterators, and
pinned-QuickJS-certified static of and from. Its scoped gate reaches
4,383/4,383 variants across 2,213 paths in both engines; the complete
conservative vector is 51,940/102,037.
TypedArray audit/admission, Uint8Array codecs, modules, SharedArrayBuffer/Atomics,
and broad built-in coverage remain incomplete. Pinned QuickJS is the test oracle,
never a product dependency; bookkeeping lives in the status documents.
Rust 1.85 or newer is required.
