This involved building a rather complex C code base (with multithreading, SIMD, callback functions and whatnot) to WebAssembly via Emscripten, and writing a minimal amount of JavaScript and HTML for the frontend.
This involved building a rather complex C code base (with multithreading, SIMD, callback functions and whatnot) to WebAssembly via Emscripten, and writing a minimal amount of JavaScript and HTML for the frontend. Since this is something we’ll do soon, we can forget about this option and just take it as a fact that the.wasm files generated by emscripten require some glue JavaScript code to actually run, but in case you are interested you can check out the official documentation. In 2018, a CPU vulnerability called Spectre was found, and it was shown that an attacker could take advantage of shared memory between the main browser thread and web workers to execute code remotely.
