I developed a terminal emulator, file manager and text editor Deodar 8 years ago in JavaScript/V8 with native C++ calls, it worked but I was extremely disappointed by speed, it felt so slow like you need to do a passport control each time you call a C++ function.
The official solutions, node-ffi and node-ffi-napi, are extremely slow, with an overhead hundred of times higher than it should be. I don't know what they do to be so slow.
I'm making my own FFI module for Node.js, Koffi, as a much faster alternative. You can see some benchmark here, to compare with node-ffi-napi: https://www.npmjs.com/package/koffi#benchmarks
Probably not since single threaded improvement has barely advanced over the last 8 years, and JS/V8 are still in a single threaded world that stopped existing a decade ago.
