Hands-On WebAssembly for C++ Programmers - Seeing WebAssembly in Action

The video tutorial explores the speed of WebAssembly compared to C and JavaScript using the Quicksort algorithm. It demonstrates compiling C code to WebAssembly and running it in a browser, highlighting WebAssembly's performance advantages. The tutorial also covers WebAssembly's text format and its integration with JavaScript, concluding with a preview of setting up a toolchain for running C applications in a web browser.
