Check out the old (and retracted) SIMD.js proposal that aimed to bring SIMD support to JS and the related offshoot that attempted to cover WebAssembly interop as well.
https://github.com/tc39/ecmascript_simd https://github.com/stoklund/portable-simd/blob/master/README.md Also, WebAssembly has a proposal, spearheaded from that work with JS, to try to bring SIMD support to it. The WebAssembly proposal is considerably lower level, but has broad implementor interest. https://github.com/WebAssembly/simd/blob/master/proposals/simd/SIMD.md Hardware SIMD and matrices may seem like two entirely different things, but a large area of overlap exists between small matrix math and CPU vector instructions. Those instruction sets were designed with coordinate, vector, and small matrix math in mind. For instance: - 2x2 matrix multiplication is maybe a dozen or so SSE instructions in modern Intel x86-64 assembly. - Scalar matrix multiplication is only a single "multiply vector by scalar" instruction. - 2x2 discriminant is a swizzle, a multiply, clear top two lanes, and horizontal subtract And even with larger data sets, vector instructions can and do help.
