Hands-On WebAssembly for C++ Programmers - Interacting with System Libraries

The video tutorial explores how scripting and WebAssembly work together to provide system library access. It covers the interaction with system libraries, handling input and output, and file systems in the browser. The tutorial delves into Emscripten's implementation of standard libraries like libc and libcxx, which are adapted for web environments. It includes a walkthrough of Emscripten's source code, highlighting how it provides a POSIX-like API. The video sets the stage for understanding WebAssembly's capabilities and prepares viewers for upcoming topics like threading and socket communication.

Explain how Emscripten modifies the API depending on whether it is in an Emscripten setting or not.

What challenges does the web browser face in accessing the file system, and how does Emscripten address these challenges?
