WASM has taken over the web-development scene in the past few years. It is a language that can be run by the web platform alongside with Javascript. Being treated as a target language, a variety of low-level, statically-typed languages such as C++ and Rust can be compiled to WASM. Thus, a variety of complex, computationally intense applications can now be tackled through readily available web applications. Demos of 2 such applications are shown in the presentation and a side-to-side comparison is done next to JS code.
