wondering if there is a way to easily map out where functions are being called from in a case base ? specifically in Jest with TS.

im trying to find out where all the functions we have are being used and if there any that are either duplicate of another (in a round a bout way) or if there are any that are not being used at all.

also to get an idea of how often functions are being called.

i have searched everything i can think of but only get results back for map() functions, not actually mapping of functions.
