What are some effective debugging techniques for WebAssembly?

Debugging WebAssembly can be challenging, but here are some effective techniques: 1. Use source maps to map WebAssembly back to the original source code. 2. Utilize browser developer tools that support WebAssembly debugging, like Chrome or Firefox. 3. Insert logging statements in your original code to trace execution. 4. Use the WebAssembly Debugging API for more advanced debugging capabilities.

Can you explain how source maps work in this context?

Source maps are files that map your compiled WebAssembly code back to the original source code, allowing you to debug using the original code instead of the binary. When you enable source maps in your build process, the browser can use them to show you the original lines of code during debugging.

What tools can I use for debugging WebAssembly?

You can use tools like Chrome DevTools, Firefox Developer Edition, and Visual Studio Code with the WebAssembly extension. These tools provide features like breakpoints, step-through debugging, and viewing the call stack.

Are there any common pitfalls to avoid when debugging WebAssembly?

Yes, some common pitfalls include not using source maps, overlooking browser compatibility issues, and failing to test edge cases in your code. Always ensure your environment is set up correctly for debugging.
