How it works...
Modern browsers provide a JavaScript engine alongside a web assembly virtual machine (https://webassembly.org/). With this capability, web applications can run binary code that is safely executed inside its own runtime environment with easy access from the outside. The main benefits include the following:
- A smaller-sized application, thanks to binary compilation
- Faster end-to-end execution times (no compilation step)
- No garbage collection—the WASM virtual machine is a stack machine
On top of that, WASM can be converted into a text-based format for visual inspection and manual optimization. Rust is one of the few languages to even compile to these formats (text and binary), and it's largely thanks to LLVM and Rust's approach ...
