Course Description

What is WebAssembly used for? WebAssembly is a new type of code that can be run in modern web browsers — it is a low-level assembly-like language with a compact binary format that runs with near-native performance and provides languages such as C/C++, C# and Rust with a compilation target so that they can run on the web.Will WebAssembly replace JavaScript? Furthermore, WebAssembly is designed to run alongside JavaScript, not to replace it. With the WebAssembly JavaScript APIs, you can run code from either language interchangeably, back and forth without any issue.Is WebAssembly faster than JavaScript? JavaScript often performs better during execution. Once fully optimized, WebAssembly is slower when executing code in the browser. And this is partly (some) browsers' “fault”: On Microsoft edge, for instance, WebAssembly executes terribly slowly.How much faster is WebAssembly? If you plan to use WebAssembly on desktop Chrome, written in AssemblyScript, for Wasm's Intended use case (Computational heavy-lifting tasks), then yes, Wasm is about 30% faster. But on mobile it can be much faster at around 60%, and on firefox it can be much much faster around 90%
