Feedback form is now closed.
WebAssembly is a new type of code that can be executed in modern web browsers through a compact binary format that runs **at near-native speed** without any plugins. This have a great impact for the web, because it gives a new way to run code from other languages into the web at near native performance, providing client apps with a technology to run high performance applications in such way that was not possible before.

WebAssembly lets you port your current code to the web. Using emscripten you can compile code written in C or Rust into WASM as target, so you can reuse your current apps or call part of the code from a JavaScript context and access browser functionalities using the same Web APIs accessible from JavaScript.

This talk will be an introduction of what's possible to do with WASM. I will discuss the following topics:

* Introduction of scenarios where high performance could be required.
* What is WASM, its components and features.
* What is tool chain to compile your code for WASM.
* Code interaction between JS and WASM (and viceversa)
* Code examples and a brief presentation of demos (video or live).
* Firefox's Dev Tools for working with WASM.
* Where you can get more information about it.

Attendees will learn the basics of this game-changer web technology, how to start to create high performance apps from scratch or migrate existing ones written in other languages like C/C++ or Rust to WebAssembly.

All by using open technologies!
