C, C++, Rust, Go, Java, C#, and other toolchains can compile to Wasm and ship it to the browser to complement JavaScript. Real-world uses include large games, Google Earth, Magnum, Blazor, and <strong>AutoCAD on the web</strong> — this post focuses on our AutoCAD case.</p> <h2 id="why-webassembly">Why WebAssembly?</h2> <p>Mainly <strong>performance</strong>. JavaScript struggles with heavy CPU/memory work, drawing, and high concurrency. The platform has added pieces like <code>SharedArrayBuffer</code>, but limits remain. We used Emscripten and asm.js, later <strong>Binaryen</strong>, for roughly <strong>12–15%</strong> overall speedup.</p>
