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.

It supports both, and they've switched back and forth on what the default should be. They also supported duktape in the past.

I always use v8, because it has better compatibility with libraries and tools.

Might be a case of outdated documentation/website: https://frida.re/news/2019/05/15/frida-12-5-released/

Interesting, it looks like there was a move from V8 to QuickJS more recently than that: https://frida.re/news/2020/10/28/frida-14-0-released/

EDIT: and then the default moved back in https://frida.re/news/2020/12/01/frida-14-1-released/
