Combining WebAssembly

Some languages need prerequisites when converted into WebAssembly. Languages like Rust, C/C++ and TypeScript can be converted into WebAssembly.

In combining WebAssembly with Node.js, the use of WebAssembly modules and native C++ addons is necessary. Almost always, everybody would like improve performance and workloads issues.

When compiling C/C++ to WASM, it’s possible to migrate existing the codebases or logic to the browser. For instance, AutoCAD and Figma both reported great performance results when embraced WebAssembly.

Combining WebAssembly with Rust, improves the performance of Node.js. Rust is a relatively new systems programming language that is supported by Mozilla. Rust offers impressive features: performance, safety, tooling and community. Besides application performance, developer productivity is also much greater with features taken from higher-level languages, easy to use syntax, and excellent compilation error messages. Regarding safety, Rust has many ways of reducing memory storage and thread.

Out of the box, a React app will not support WebAssembly. In order to change that, you will have to make some changes to underlying webpack config that powers the app.

In general, there could be a performance gain in writing code in C or Rust over Python. Python is not compiled to WASM, but its interpreter. Python is not a compiled language, it is a script language. There are two popular Python runtimes/interpreters that support Python: pyodide and WASM port for micropython. Both of them are runtimes that translate Python into their own bytecode and then they execute bytecode in WASM.
