ELI5: Imagine you want to run a heavy, powerful 3D video game engine inside a standard web browser or a lightweight desktop app, without making it slow or unsafe.

JavaScript alone can't handle that kind of heavy lifting efficiently. That’s where Wasm comes in. It lets you run high-performance native code (like C++) at near-native speed safely in the sandbox.

For example, I'm currently using Wasm to run a complex 3D geometry engine (Manifold) inside a lightweight CAD app (Nasscad). It gives you web flexibility with desktop power.

I started working on Nasscad back in early March with the assistance of Claude AI, and it led to Nasscad: a lightweight, powerful, and uncompromising CAD tool. I used to be allergic to HTML, Node.js, and the like. But we have to face the reality that the web stack dominates now—bringing along HTML, CSS, JavaScript, Wasm, frontend, and backend.
