Hands-On WebAssembly for C++ Programmers - Debugging WebAssembly

The video tutorial explains the powerful capabilities of debuggers in web browsers, focusing on setting breakpoints, inspecting variables, and modifying control flow. It discusses different levels of debug information and the importance of source maps. The tutorial provides a step-by-step guide to using the debugger in Chrome and highlights the benefits of using both Chrome and Firefox for debugging WebAssembly. The video concludes with insights into the future of debugging tools and their expected improvements.

What is one of the main advantages of using a debugger over print-style debugging?

• It automatically fixes bugs in your code.

• It enables you to pause code execution and inspect variables.

• It provides a visual representation of your code.

• It allows you to write less code.

What does the dash G flag do when configuring a web browser debugger?

• It compiles the code into a different language.

• It encrypts the code for security.

• It provides different levels of debug information.

• It optimizes the code for faster execution.

Why are source maps important in web debugging?

• They automatically update your code with new features.

• They provide a backup of your code.

• They translate web executable files back to their original language.

• They increase the speed of code execution.

What is a limitation of current WebAssembly debugging tools?

• They automatically crash when used.

• They lack comprehensive variable inspection capabilities.

• They do not support any programming languages.

• They cannot be used in any web browser.

How can Chrome and Firefox be used together in debugging?

• By running them simultaneously to compare execution speeds.

• By using Firefox to view WebAssembly text and Chrome for variable inspection.

• By using Chrome for coding and Firefox for testing.

• By using both to encrypt and decrypt code.

What is the benefit of viewing both C and JavaScript in the same call stack?

• It allows for faster code execution.

• It provides a unified view for easier debugging.

• It automatically translates code between languages.

• It reduces the size of the codebase.

What is expected to improve as WebAssembly grows?

• The functionality and features of web debugging tools.

• The user interface of web browsers.

• The security of web applications.

• The speed of web browsers.
