Hands-On WebAssembly for C++ Programmers - Integrating WebAssembly Modules

The video tutorial explains the concept of modules in WebAssembly and Emscripten, detailing how they are structured and instantiated. It covers the Emscripten module API, highlighting its ability to override default behaviors like printing. An example is provided to demonstrate how to redirect standard output to the developer console. The tutorial also lists various module functions available in Emscripten, such as file system functions, memory management, and C function interoperability, emphasizing the API's utility in interacting with WebAssembly from JavaScript.
