WebAssembly is a lightweight virtual machine designed to execute portable bytecode at near native speed. You can compile Rust or C/C++ functions to WebAssembly bytecode, and access those functions from TypeScript.
What about applications that require even higher performance, such as AI-as-a-Service applications that need to execute complex neural network models in sub-seconds? For example, an IBM study found that Rust and WebAssembly could improve Node.js execution speed by 1200% to 1500% for certain data processing algorithms.
Deno loves WebAssembly and we implement in Wasm:
> In fact, some popular Deno components are already implemented in WebAssembly. For example, the sqlite module in Deno is created by compiling sqlite’s C source code into WebAssembly using Emscripten. The Deno WASI component enables WebAssembly applications to access the underlying operating system resources, such as the file system. In this article, I will teach you how to write high performance Deno applications in Rust and WebAssembly. page
