JavaScript Frontend frameworks have undoubtedly helped to push the boundaries of what was previously possible in the context of a browser. It uses the native Rust support for compiling to wasm32 and does not require Emscripten. This library allows WebAssembly modules to be loaded in binary format and their functions invoked. One example is a technology specification called WebAssembly (WASM), which allows web apps to work at near native speed, and to tap into performance code or language so users don't ever feel like they left their environment. I've also been struggling to handle the low-bandwidth interface between JS and WASM. WebAssembly is yet more ambitious, though!
