Debugging Typescript code with line numbers

When opening the console in a browser, typically the javascript line number of a function call or error message is displayed.

However, my current setup involves using TypeScript, which gets compiled to Javascript.

I am wondering if there is a way to retrieve the line numbers for TypeScript instead?

My primary editor is VSCode.

Source maps are available, but the easiest approach is to directly navigate to the source code. This works well for non-uglified and unminified development environments. However, if the code has been uglified or rollified, then source maps become necessary.

Alternatively, you can simply analyze the generated JavaScript file to identify any issues in the source code. If this process seems complex, you always have the option to view both the source code and the built JS side by side for easier understanding.
