Whenever I explore a library, I do the same, but when I think of CRUD functions I always look for these first in this general order: - Create methods - Delete methods - Update Methods - Read Methods Creating and deleting things are usually the easiest starting points. You always have an idea on how an app does this so its pretty easy to figure what things you need to do to trigger the breakpoint. Usually the create and delete methods are named something obvious so grepping for it is not terribly difficult If you work with JS libraries there is always some demo website, you can check for any event listeners on that element too, set breakpoints go from there.
