WebAssembly will be the next big thing in IT and in Web Developement world. But web developlemnt is a JavaScript doman. What it has to do with .NET and C#? Well Microsoft is experimenting with Blazor and other companies and community members with different aproaches like Ooui and Uno. All of that sits on top of Mono!

  6. 6. Hypertext, HTML, HTTP Text displayed on a electronic devices with references (hyperlinks) to other text that the reader can immediately access. Hypertext documents are interconnected by hyperlinks, which are activated by a mouseClick, keypress set or by touching the screen. „Hypertext" is also used to describe tables, images, and other content formats with integrated hyperlinks. Hypertext is one of the key underlying concepts of the WorldWide Web, where Web pages are often written in the Hypertext Markup Language (HTML). As implemented on the Web, hypertext enables the easy-to-use publication of information over the Internet. The HypertextTransfer Protocol (HTTP) is an application protocol for distributed, collaborative, and hypermedia information systems. HTTP is the protocol to exchange or transfer hypertext.

  15. 15. Different way the same language there is a LOT of JavaScript Todays JavaScript JavaScript is the language of the Web But it’s not very good Assembly Language (still human readable simple language)
  16. 16. WebAssembly is not designed to replace JS, but to coexist A new low-level binary format for the web (WASM) It’s a bytecode for web (compilation target) WebAssembly What? Sandboxed runtime in JS virtual machine Supported in all big browsers
  17. 17. A low-level binary format WebAssembly Why? Offer maximized performance Security it runs locally so it's more secure Compiled from other languages
  18. 18. WASM opens possibilities for other languages
  19. 19. Emscripten is a source-to-source compiler that runs as a back end to the LLVM compiler and produces a subset of JavaScript known as asm.js. It can also produce WebAssembly. This allows applications and libraries originally designed to run as standard executables to be integrated into client side web applications. asm.js can be compiled by browsers ahead of time meaning that the compiled programs can run much faster than those traditionally written in JavaScript. WebAssembly How?
