About

Why does detectives use regexp?

Parsing the code and analyzing the generated ast would work way better, but it requires a lot of code, which means you would have huge bundle sizes and it would probably not work in the browser, since most js parsers are built for node.

detectives uses regexp, so it is really fast while being very small.
