  1. How Use The Fourth Language Code Hello, WebAssembly

  3. WebAssembly 5W1H

  4. What is WebAssembly? • 4th Language for the Web •

    Virtual Instruction Set Architecture (V-ISA), Linear Memory, Implicit Stack, Some Instructions • Bytecode • No functions for operation system access and built-in • Code with programming languages, C/C++, Rust, Go, AssemblyScript, ... • Browser, and beyond browser, V8, SpiderMonkey, Wasmer, Wasmtime, Lucet, Cranelift, Nodejs, Python, Deno ...
  5. Why is WebAssembly fast? • Bytecode, compiled and Optimized by

    low-level language • Li ff o ff runs Wasm immediately and TurboFan runs further optimized machine code without observing • Optimized machine code can be running at near native speed • E ffi cient memory management • Use 'better' a programming language to solve a certain problem

  9. When to use WebAssembly? • Predictable performance • E ffi

    cient memory management • Rooms for performance improvement • Taking advantages of low-level languages, SIMD, Multithread, Popular and certi fi cated libraries
  10. Who should learn WebAssembly? • Developers for Multimedia or Graphic

    tools on browsers, ex) fi gma • Full-stack engineer in case of serverless, lambda, or edge computing • Games on browsers, ex) unity • Desktop application developers who want to port it • Developers who would like to use popular libraries written by low-level language • Basic knowledge of HTML Javascript and be passionate about performance improvement on the Web
  11. Where to use WebAssembly? • Video player or editor •

    Image viewer or editor • Games • Vision processing • Music player • Encryption • Edge computing

  24. How to get started with WebAssembly? • Pick up a

    low-level language like C/C++, Rust, AssemblyScript, C# or Go • Find out toolchain to compile to wasm: • C/C++: Emscripten • Rust: rustc with wasm32 target, or cargo, or wasmtime, ... • AssemblyScript: acs • Go: Build with Wasm architecture • Try out WebAssembly frameworks, like yew.rs • Learn how to use tools and debugger for WebAssembly
  25. • Rust with the latest version • Ready to build

    wasm and wasi • wasmtime, wasm-pack, binaryen, wabt • Dev server (ft. serve) WebAssembly Starter Kit with Rust
  26. • Hello World • DOM Access with wasm- bindgen •

    Fetch • SIMD • Multithread • WASI (WebAssembly System Interface) WebAssembly Starter Kit with Rust
