What is WebAssembly / WASM?

WebAssembly (abbreviated Wasm) is a binary instruction format for a stack-based virtual machine.

Wasm is designed as a portable target for compilation of high-level languages like C/C++/Rust, enabling deployment on the web for client and server applications.

History OF WASM

Inspired by asm.js

BROWSER SUPPORT FOR WASM

WHY CARE

• It's a binary format smaller to deliver than JS
• It opens up use-cases that were difficult to achieve with JS like: video games, video editing, 3D rendering, or music production
• It's lower-level language so the runtime has less work to do
• Compile target from many other languages C#, C++, JAVA, GOLANG, ELM, RUST 
• Native browser support

You can compile other languages to it 

Write the textual version of WASM yourself .wat

HOW TO GET STARTED

Import wasm modules from JS and use them**

Elm, C++ emscripten, Blazen .NET, Turboscript
