...'mostly works' describes pretty much every debugging experience outside Visual Studio. But I really can't complain, I've set up 'F5-debugging' in VSCode, pressing F5 starts a local web server, starts Chrome with the debuggee, and starts a remote debug session in VSCode and stops at the first breakpoint (and interestingly all this happens 'immediately', while debugging a native Cocoa macOS app via LLDB easily takes 5 to 10 seconds until the first breakpoint is reached).

TL;DR: It works just fine (early versions of the DWARF extension had problems catching 'early breakpoints' but that had been fixed towards the end of 2024.
