Search engine for javascript or / and css on source code snippets

Question

it's not a programming issue per se, but still ...

does anyone know about a service / spider / crawler that can extract javascript or CSS resources embedded with standard methods (or lazy loading, no matter what it can handle)

practical use for it: search for a unique piece of code from a class or function that you wrote, and get a list of sites that link to it. or, for that matter, look for something unique from the frame and get an idea of ​​its popularity.
