I don't think I have any of gdb, but I was just talking about a hobby project using frida! Frida is a tool that lets you inject v8 into any process, then exposes a javascript debugging api, I find it incredibly useful.
Wow, that is very interesting. The docs say it is injecting QuickJS though, not v8?
> Frida’s core is written in C and injects QuickJS into the target processes, where your JS gets executed with full access to memory, hooking functions and even calling native functions inside the process.
