Letter for students

If you are a web developer, you might have heard about WebAssembly already. Don’t worry! It will not replace JavaScript. So you can continue learning it. On the contrary, it will perfectly complement JavaScript. It will bring features to the browser that never seemed possible before.

Assuming you’d want a better image compression algorithm. Some or all browsers lack the implementation. You may seek for available algorism implementations, usually available in C or C++. Or you may write your own. Either way, you'll bring it to the web through WebAssembly. And once you've done that, all your browsers can run it.

WebAssembly is usually associated with C or C++. This is not that hard to explain. emscripten required to port code to WebAssembly already existed. This is how AutoCad or full gaming engines like Unity were ported to the web. This wasn’t possible before WebAssembly.

But any language may find it’s way to the web through WebAssembly. Rust is already a popular, Mozilla being actively involved in WebAssembly. AssemblyScript, a strict subset of TypeScript, is another programming language. It allows web developers to code with WebAssembly and skip the very different C or C++ coding mindsets. Microsoft’s C# is one of the latest entries in the WebAssembly world since the Brazor release.

WebAssembly doesn’t have yet a garbage collector. They’re working on the standard. And among, other drafts, there is even more support for:

If you still can’t find a way to use WebAssembly today, look at your web performance bottlenecks in the browser. This seems to be the main opportunity insert WebAssembly into current web apps.


We’ve already made an overview of WebAssembly. It was focused for entry level in the IT industry. People who are curious about technology in general. We usually do that with every Letter for students and we do our best to have a letter for students for every technology. And by student we mean those people who don’t know from where to start and struggle in making their way …

About WebAssembly

WebAssembly (often shortened to Wasm) is an open standard that defines a portable binary code format for executable programs, and a corresponding textual assembly language, as well as interfaces for facilitating interactions between such programs and their host environment. The main goal of WebAssembly is to enable high performance applications on web pages, but the format is designed to be executed and integrated in other environments as well.Wasm does not replace JavaScript; in order to use Wasm in browsers, users may use Emscripten SDK to compile C++ (or any other LLVM-supported language such as D or Rust) source code into a binary file which runs in the same sandbox as regular JavaScript code; Emscripten provides bindings for several commonly used environment interfaces like WebGL; it has access only to an expandable memory and a small number of scalar values. There is no direct Document Object Model (DOM) access; however, it is possible to create proxy functions for this, for example through stdweb, web_sys, and js_sys.The World Wide Web Consortium (W3C) maintains the standard with contributions from Mozilla, Microsoft, Google, and Apple. == History == WebAssembly was first announced in 2015, and the first demonstration was executing Unity's Angry Bots in Firefox, Google Chrome, and Microsoft Edge. The precursor technologies were asm.js from Mozilla and Google Native Client, and the initial implementation was based on the feature set of asm.js.In March 2017, the design of the minimum viable product (MVP) was declared to be finished and the preview phase ended. - read more on Wikipedia
