Web browsers and web sites have been around for quite a while. Javascript has been the language driving those pages but there's a way to write in a lower-level language and speed up the slow parts without losing cross-platform compatibility. That way is called Web Assembly (WASM). In this episode we dig into exactly what that is.
Show notes:
Take-aways from the episode:
- If you have a compute intensive part of your web application, it may make sense to implement that bit of code in a compiled language like C, C++ or Rust and then compile them to WASM so they can be executed in the browser.
- Security and Portability. WASM code is secure as it utilizes the browsers' sandbox and portable as all browsers are supporting the W3C Standard WASM.
- You are almost certainly using WASM based applications. It's in use in Google Maps & Docs, Netflix, Spotify, Amazon and many more.
