WebAssembly Beginner to Advanced from Udemy

In this course you will learn what WebAssembly is, how can you use it and benefit from its capabilities.

This is a brand new technology which lets you to run your C/C++, Rust, AssemblyScript code (and many more to come) on the web by using assembly-like binary files.

You will learn:

To compile your C/C++ code to the WebAssembly binary format (wasm) using online compilers, and after this, the Emscripten toolkit locally.
The low-level building blocks of a WebAssembly module
The WebAssembly Text Format (wat) and use it to solve complex problems
How to use the Emscripten Module object and the generated glue code
Call C/C++ functions from JavaScript and vice-versa
Debug and launch the Emscripten web server
Compile a Qt project to WebAssembly

If you want to be a part of the future of the web development, this is the best place for you to start. You will get to an advanced level of using the web assembly technology in no time.

It is recommended to have a basic understanding of Javascript and C/C++, but this course is beginner friendly, so it shouldn't be hard to understand for anybody. We will focus on both theory and practice to make sure you both understand the concepts and can apply them.
