It's very common to use GDB with Asm, but only when combined with some plugins. Nowadays this is mostly done when reverse engineering software, or when testing low-level memory corruption exploits.

The screenshots of this popular gdb plugin are a good example: pwndbg.re/stable/features

When a web app fails I sometimes check if it's a chrome app. Yours seems one.

Just kidding. Check it out on Firefox and look at Inspector console.
