Debugging the game

To debug a traditional program, be it in Java, C#, or C++, we must set breakpoints and step through the code. In JavaScript, we can type the word debugger to set a breakpoint, but although WebAssembly runs in the browser, it isn't JavaScript. So, how do we debug it?

There's a lot of conflicting information about debugging with WebAssembly. How do you debug WebAssembly? Well, according to the official Rust WebAssembly documentation, it's simple – you can't!

Unfortunately, the debugging story for WebAssembly is still immature. On most Unix systems, DWARF is used to encode the information that a debugger needs to provide source-level inspection of a running program. There is an alternative format that encodes similar information on Windows. Currently, there is no equivalent for WebAssembly. Therefore, debuggers currently provide limited utility, and we end up stepping through raw WebAssembly instructions emitted by the compiler, rather...
