Hands-On WebAssembly for C++ Programmers - Catching WebAssembly Traps

The video tutorial explains WebAssembly traps, which occur during exceptional events like divide by zero. It discusses how LLVM handles traps through clamping and provides examples using JavaScript try-catch blocks. The tutorial highlights differences between WebAssembly and JavaScript in handling divide by zero, where WebAssembly throws a runtime error, while JavaScript returns Infinity. It also covers exception handling, noting that exceptions do not bubble up to JavaScript by default but can be enabled with specific compile options. The video concludes with a look at future improvements in WebAssembly's native exception support.
