Why Does Visual Studio Code Debugger Start So Many Threads?

As developers, we're no strangers to the world of debugging. It's a crucial step in the software development life cycle that helps us identify and fix defects in our code. However, many of us may have wondered why Visual Studio Code (VS Code) debugger seems to start so many threads during the debugging process.

To understand this better, let's take a closer look at some of the features offered by VS Code debugger. Features like error listing, adding breakpoints, visualizing program flow, controlling execution, data tips, and watching variables are all essential tools for debugging code effectively. But did you know that these features require multiple threads to function properly?

When you start the debugger in VS Code, it creates a separate thread for each feature mentioned above. This means that if you have 5 breakpoints set, for instance, the debugger will create 5 separate threads to monitor those breakpoints. Similarly, if you're using data tips and variable watches, additional threads will be created to facilitate these features.

Now, you might be wondering why this is necessary. The reason is that VS Code is designed to provide a seamless debugging experience by offering advanced features that can help you identify defects quickly. By creating multiple threads for each feature, the debugger can ensure that it doesn't interfere with your code's execution while still providing the information you need to debug efficiently.

However, this may lead to a situation where the debugger starts many threads, which can sometimes be overwhelming. But fear not! VS Code provides a solution for this as well. You can use Break Point Filter, a feature that allows you to filter out specific breakpoints and only focus on the ones that are relevant to your debugging needs.

In conclusion, the reason why Visual Studio Code debugger starts so many threads is due to its advanced features designed to provide an efficient debugging experience. While it may seem overwhelming at first, using features like Break Point Filter can help you manage multiple threads and focus on the task at hand – finding and fixing defects in your code.
